N2 - This paper analyzes the conversion time of a time domain digital pixel sensor based on pulse width modulation scheme. Two quantization schemes are studied namely the Uniform Time domain (UQ) and the Non Uniform Time domain (NUQ) quantizers. It is shown that the latter scheme not only permits to linearize the non-liner response of a PWM vision sensor but also allows to significantly speed-up the conversion time particularly for wide dynamic range and lower coding resolution. The VLSI architecture of a reconfigurable DPS for variable spatial and coding resolutions is proposed in 1-poly, 5 metal CMOS 0.35μm n-well process.
