Abstract :
A 6-bit time-interleaved analog-to-digital converter for ultra-wide band applications is proposed. The structure consists of seven successive approximation A/D converters designed to pursue high speed and low power consumption. A merged-capacitor technique is implemented in the DAC, while the successive approximations register is based on a single-row architecture with D-FF´s. The converter, designed in ST 90nm CMOS technology exhibits a maximum sampling frequency of 1.2 GHz at 1 V supply with a 500 mV input range and 16 mW of power consumption. The simulated figure of merit is 0.3 pJ/conv
