• abstract: An all nMOS image sensor with a wide dynamic range (WDR) response has been designed. In particular an improve d scheme to obtain a user-controlled logarithmic response with a 120 dB dynamic range from an integrating pixel is described. This scheme requires a time modulated input reference to the pixel and a method to generate this reference voltage on chip is proposed as an alternative to previous off-chip voltage generating solutions. An array of 256×256 of 5×5 μm2 pixels and the reference voltage generator have been fabricated using a 180 nm 1P6M CMOS process.
