ABSTRACT:
An analog-to-digital converter with all parallel BiCMOSs are provided. Comparators each composed of a plurality of bipolar transistors are included for comparing an analog signal with a reference voltage. A transfer circuit comprising a plurality of CMOS transistors are provided for transferring an output from the comparators to a corresponding input mode. A plurality of first ROMs and a second ROM, each of which is composed of a plurality of CMOS transistors, provide outputs of digital signals coded by the transfer means.
