Abstract:
An electronic device is provided such as a programmable rise/fall time control circuit, for example, that delivers a continuous and near linear rising/falling slope of a control signal, with programmability that can be implemented in future CMOS image sensor devices. This device includes a programmability block for reset or transfer gate signals. The programmability block includes two inputs: an input bias current and a signal from the control bits. The programmability block further includes two similar internal circuit blocks, one for generating a fall time control signal, and one for generating a rise time control signal. Additionally the programmability block includes two outputs; a fall time control signal, and a rise time control signal. The device further includes a reset or transfer gate buffer configured as an inverter. The reset or transfer gate buffer includes three input signals: The fall time control signal and rise time control signal from the programmability block, and an INT Reset signal. Furthermore, the reset or transfer gate buffer includes an output reset or transfer gate signal. The device is configured to take an input bias current, and by controlling the transconductance of internal circuitry provide a tapered rise and fall time signal to a reset or transfer gate of a CMOS image sensor that is programmable.

Abstract:
An exemplary CMOS image sensor comprises a reset transistor, a photodiode, reset drain voltage circuitry, and reset gate voltage circuitry. A cathode of the photodiode is connected to a source of the reset transistor, and an anode of the photodiode is connected to ground. The reset drain voltage circuitry is connected to a drain of the reset transistor, and the reset gate voltage circuitry is connected to a gate of the reset transistor. During an exemplary hard reset operation, the reset drain voltage circuitry supplies a first drain voltage to the drain of the reset transistor in accordance with a determined level of light for exposure, which is determined dynamically. According to another exemplary reset operation, a hard reset phase is immediately followed by a soft reset phase.
Abstract:
An exemplary CMOS image sensor comprises a plurality of pixels arranged in an array. The plurality of pixels includes a first pixel proximate an optical center of the array, and a second pixel proximate a peripheral edge of the array. The CMOS image sensor further comprises a first metal interconnect segment associated with the first pixel situated in a first metal layer, and a second metal interconnect segment associated with the second pixel situated in the first metal layer. The second metal interconnect segment is shifted closer to the optical center of the array than the first metal interconnect segment so that the second metal interconnect segment approximately aligns with a principle ray angle incident the second pixel, thereby reducing pixel light shadowing.
