12-Bit 10 MHz BiCMOS Comparator

摘要

The design of a self-calibrating BiCMOS comparator is presented. The circuitemploys a preamplifier followed by two regenerative stages to achieve an input offset of 200 mV at a conversion rate of 10 MHz. The comparator has an input range of 3 V and dissipates 1.7 mW from a 5-volt supply. analog-to-digital converter comparator BiCMOS
