Abstract: An active pixel sensor a plurality of sensor pixels disposed in a row, a plurality of sensor pixels in a column, and steering circuitry coupled to each of the sensor pixels. Each of the sensor pixels includes a first pixel circuit, and a second pixel circuit. For each of the sensor pixels, the steering circuitry includes a first switch, a second switch, a third switch, and a fourth switch. The first switch and the second switch are connected in series to route an input signal to the first pixel circuit. The third switch and a fourth switch are connected in parallel to route the input signal to the second pixel circuit.

Abstract: In at least one example, a circuit includes an amplifier, a first feedback loop, and a second feedback loop. The amplifier includes an amplifier input and an amplifier output. The first feedback loop includes a first feedback capacitor and a first switch. The first feedback loop is coupled between the amplifier input and the amplifier output. The first feedback capacitor is coupled to the amplifier output through the first switch. The second feedback loop includes a second feedback capacitor and a second switch. The second feedback loop is coupled in parallel with the first feedback loop between the amplifier input and the amplifier output. The second feedback capacitor is coupled to the amplifier input and to the first feedback capacitor through the second switch.
