A 12 bit 5 μsec CMOS recursive ADC with 25 mW power consumption

A 12-bit 5-μs CMOS analog-to-digital converter (ADC) has been realized in a 4-mm

area with power consumption of only 25 mW ADC with 25 mW at a supply voltage of 5 V. Trimming and software calibration were not used. A four-step recursive subranging architecture has been adopted
