• abstract: This letter introduces a Gm-cell-based CMOS image sensor (CIS) achieving deep subelectron noise performance. The CIS presents a new compensation block and low-noise current source to improve the performance of the Gm pixel. Furthermore, an optional first-order IIR filter is implemented to improve the output swing. The conversion gain, full well capacity, and dynamic range of the CIS can be easily adjusted by the charging time and the filter mode for different applications. The prototype chip is fabricated in a standard 180 nm CIS process and has a deep subelectron read noise of 0.31e-rms at minimum (of the noise distribution) and 0.42e-rms at peak (of the noise distribution). A smooth and clear photon-counting histogram is observed.
