Abstract
PURPOSE:To attain a high accuracy, high speed and low power consumption each for the A/D converter, by constituting the front step of the comparator with the bipolar transistor and the rear step and its subsequent units with the CMOSFET each. CONSTITUTION:The units at the front step of the comparator, such as emitter followers 31 and 32 which increase the input impedance, diodes 33 and 34 for level shift, differential amplifiers 35 and 36 to read in the input differential signals, constant current transistors 42-46 and others, are constituted with bipolar transistors TR. On the other hand, the units after the rear step such as pulse amplifier 47, latch circuit 71 and NAND gate 90 are constituted by the CMOSFET. Thus the bipolar transistor suited for the high-accuracy and high-speed operation is combined to the CMOSFET suited to the low power consumption to attain a high speed, high accuracy and low power consumption for the A/D converter, in particular, the parallel-type converter.
