摘要:
The present invention relates to an analog to digital converter, comprising: a reference voltage generation circuit (143) for generating a plurality of reference voltages having different voltage values, and a plurality of comparators (COP1d - COP255d) each including a first emitter follower stage (131) to which an analog input signal is supplied, a second emitter follower stage (132) to which one of the plurality of reference voltages is supplied, and a differential amplifier (133) for amplifying a difference between outputs of said first and second emitter follower stages (131; 132). Output terminals of the first emitter follower stages (131) are connected common between said plurality of comparators (133), and output terminals of the second emitter follower stages (132) are connected common between each adjacent ones of said plurality of comparators by way of a resistor (R152).
