This paper proposes a logarithmically responsive pixel structure based on a charge compensation technique. The structure retains a high-conversion-gain (HCG) node while introducing a PN junction at the low conversion gain (LCG) node. Under very high light intensity conditions, a large amount of overflow charge makes the LCG node voltage decrease continuously, which results in this PN junction gradually transitioning from reverse bias to forward bias. Moreover, the forward bias current compensates for the photogenerated current by extracting electrons, which moves the pixel from the linear phase to the logarithmic phase and extends the dynamic range. Simulation results demonstrate a linear dynamic range of 97.76 dB and a logarithmic dynamic range of 55.14 dB for the pixels, thus achieving a combined dynamic range of 152.90 dB.
