Abstract
Ping-pong readout architecture allows for faster frame rates in CMOS image sensors. However, various problems are created by this architecture due to cross-talk between components. Provided herein are novel ping-pong readout layouts which better isolate components to reduce crosstalk issues. Also provided herein are novel timing schemes for operating ping-pong readout circuits which prevent crosstalk signal spikes or readout corruption.
