摘要： An analog to digital converter comprises a differential input portion that receives an input voltage and a reference voltage and has a first and second output terminals, a positive feedback portion connected to said first and second output terminals, a buffer if CMOSFETs connected at its input to the first output terminal, a second buffer connected at its input to the second output terminal, and a comparison circuit including a first switching portion connected between the first and second output terminals for connecting and disconnecting the first and second output terminals in response to a comparison clock signal. The comparison circuit is connected at its output to the first or second buffer. The input voltage and the reference voltage are compared when said switching portion changes from the connecting condition to the disconnecting condition in response to the comparison clock signal.
