A time-interleaved four-channel pipeline analog-to-digital converter is presented. The A/D converter utilizes a double-sampling, low power, high speed operational amplifier. The maximum sample rate of the converter is 400 MS/s. With a 3.3 V supply voltage, a power consumption of 170 mW is achieved. The circuit is designed with a 0.35 μm BiCMOS process and for a full-scale 147.7 MHz input the spurious-free-dynamic-range is 47.8 dB.
