(a, left) pVC transimpedance amplifier measurement setup. (right) Measured transimpedance with 2.5-ms Iin pulse inputs (Vs,1: 1.0 ∼ 2.4 V). (b, left) Transimpedance gain, RTIA vs. frequency for 32 pixels for fSC,pVC = 37.6 kHz and 75.3 kHz. (right) Input referred current noise for 3 pixels. (c) Median RTIA and Vamp voltage noise of 128 pixels sharing an output multiplexer.
