Abstract :
A novel current mode latched comparator designed for high speed and low-voltage, low-power applications is presented. It achieves a sampling speed of 200 Ms/s with 8 bit resolution and 3 V power supply. Its very low kickback noise makes if especially suitable for A/D converters with low supply voltage and differential operation. Moreover, it supports 2× or 4× interpolation in current mode at full clock speed, allowing a further reduction of power consumption of the entire converter
