AI Technical Summary
Existing electronic circuits with push-pull buffer circuits and track-and-hold circuits for signal readout in CMOS image sensors face high power consumption due to slow initial response and increased IR drop during bias voltage sampling, leading to inefficient power usage and potential signal readout accuracy issues.
Incorporating a switch for intermittent signal output and a bypass current circuit in the push-pull buffer circuit to form a bypass current path during signal output suspension, reducing power consumption by controlling the operation of transistors and minimizing continuous current flow.
This configuration reduces power consumption by minimizing continuous current flow and improving signal readout efficiency, addressing the inefficiencies in existing circuits by enabling faster response times and reducing IR drop, thus enhancing signal accuracy and simplifying wiring design.
