Abstract :
A 450 MS/s, 6-bit CMOS folding and current-mode interpolating A/D Converter is designed in a 0.5 μm standard digital CMOS process. A differential T/H circuit with the offset compensative amplifiers is proposed which can improve sample precision. The converter´s power dissipation is simulated as 190 mW from a 5 V supply. The latency between input and output is 2.5 clock cycles.
