<p>A pixel circuit having a global shutter and transistor circuit sharing for CMOS image sensors. In one embodiment, a shared circuit includes a reset transistor, an amplifier transistor, and a readout transistor. At least two photodiode signal generation circuits share the shared circuit, wherein each signal generation circuit includes a capture transistor, a hold transistor, and a transfer transistor. Each pixel generation circuit may also include a photodiode reset transistor. In an alternate embodiment, each signal generation circuit does not include a separate transfer transistor, instead, the transfer transistor is part of the shared circuit.</p> |
