ABSTRACT:
An N-bit asynchronous successive approximation analog-to-digital converter is provided for converting an analog signal to a binary coded representation thereof. The analog-to-digital converter employs N inverting amplifiers. Each of the inverting amplifiers receives a scaled analog input signal and provides a one bit output of the binary coded output. The scaled analog input signal applied to each inverting amplifier includes an analog input signal and feedback signals from each of the inverting amplifiers which provide a more significant output bit of the binary coded output. Each inverting amplifier thereby provides an output dependent upon the amplifier's threshold voltage which output provides one bit of the binary coded representation. In addition, each inverting amplifier may further be adapted to receive a reference signal.
