Abrégé

Techniques are described for discrete-time self-capacitor sensing in a touch panel. The self-capacitor manifests a detectably different capacitance based on presence or absence of a local touch event on the touch panel. In a first time phase, embodiments charge a self-capacitor and initialize a ramp bias generator. In a second time phase, embodiments discharge the self-capacitor with a ramp-controlled current source that is biased by the ramp bias generator to produce a discharge current that transitions from high at the beginning of the second time phase to low at the end of the second time phase. By the end of the second phase, the remaining charge in the self-capacitor depends on presence or absence of a local touch event. Some embodiments convert the remaining charge to an amplified sense output for readout.

Abrégé

Techniques are described herein for phase modulation and interpolation that support high phase modulation resolution with high linearity. Embodiments receive a digital signal that uses a sequence of K-bit digital codes to encode a sequence of instantaneous phases for phase-modulating a local oscillator signal. A fractional divider divides a reference clock into N divided clock signals at equally spaced phase intervals and selects a pair of such signals based on first designated bits of the digital code. A fractional divider-calibrated delay line generates M delayed clock signals at equally spaced phase intervals between the selected pair of divided clock signals, and selects a pair of the delayed clock signals based on second designated bits of the digital code. A digital controlled edge interpolator generates a delayed local oscillator output signal by interpolating between the selected pair of delayed clock signals based on third designated bits of the digital code.

Abrégé

Techniques are described for using an alternating-current-mode (AC-mode) bridge for low-noise self-capacitor sensing in a capacitive touch panel array integrated with a display panel. Each channel of the array has a self-capacitance (Ci) that changes responsive to presence or absence of a local touch event local. Pairs of channels are read out differentially by coupling pairs of channels to branches of an AC-mode bridge. The AC-mode bridge includes current sources that drive each branch (and thereby each channel) with a sinusoidal current, manifesting a branch voltage on each branch based on the self-capacitance of the branch. The branch voltages are used to generate an output voltage. The sinusoidal current is controlled by comparing a driver signal with feedback from the branches, so that common-mode noise on the channels becomes a common-mode component of the sinusoidal currents and is rejected in the generation of the output voltage.

Abrégé

Techniques are described for non-invasive, dual-altitude-based measurement of blood pressure of a user using a portable electronic device having a sensor head. Illumination is projected into a body part and received by photodetectors. A changing amount of illumination received by the photodetectors changes corresponds to a changing amount of blood volume in elastic circulatory system pathways in the body part. Measurements of the received illumination are obtained at multiple altitudes relative to the user's heart. A linear fit is applied to the multiple measurements based on at least a predetermined slope-calibration factor to obtain a slope-corrected mean blood pressure measurement (BPM). Some embodiments use similar techniques to further measure pulse-to-mean (PTM) at multiple altitudes. The PTM measurements are used to simulate a systolic and/or diastolic BPM.

Abrégé

Binnable time-of-flight (ToF) pixels are described, such as for integration with image sensor pixels. Each binnable ToF pixel includes a central dump gate and sub-pixels that are nominally mirror-symmetric and identical around the dump gate. Each sub-pixel includes a photodiode region (or a respective portion of a photodiode region), a storage gate, a storage region, a transfer gate, and a floating diffusion (FD) region. In an array, the binnable ToF pixels are arranged to share FD regions with other binnable ToF pixels of the array. In an un-binned mode, each sub-pixel can integrate photocharge in its storage region until it is time for readout, at which time the photocharges can be transferred to its respective floating diffusion region for individualized readout. In a binned mode, sub-pixels can integrate photocharge directly in their FD regions, which facilitates charge binning of integrated photocharge from all sub-pixels sharing the same FD region.

Abrégé

An imaging pixel design is provide with a photo-sensor block structure that facilitates dynamic control of well capacity in the photodiode region (i.e., a “well capacity adjustment (WCA) gate photo-sensor block”). The photodiode region includes a doped well in which photocharge is accumulated responsive to exposure to incident illumination. The capacity of the well corresponds to a well potential. WCA structures (e.g., deep trench regions) form walls at least partially surrounding and capacitively coupling with the doped well, such that biasing of the WCA structures changes the well potential and the corresponding well capacity. As such, the WCA structures can be biased during integration to increase the well potential to a high level for large well capacity, and the WCA structures can be differently biased during photocharge transfer to decrease the well potential to a sufficiently low level that avoids lag and/or other conventional concerns.

Abrégé

Techniques are described for non-invasive, cuff-less measurement of blood pressure of a user using a portable electronic device. Illumination is projected through a body part and received by photodetectors on the other side of the body part. The body part includes elastic pathways of the circulatory system through which blood flows. Cycles of contraction and relaxation by the heart cause pulse waves to travel through the blood, which cause volumetric changes in the elastic pathways. The transient changes in blood volume result in corresponding transient changes in the amount of illumination that is absorbed by the body part versus the amount that passes through to the photodetectors, as manifest by a detection output signal. Calibration data can be used to convert the detection output signal to blood pressure measurements, such as including diastolic and systolic blood pressure readings.
