Analog input circuit with common mode compatibility to both supply nodes |
摘要 |
An analog input circuit may include a pair of differential transconductance input stages having input nodes connected in parallel and which are fed the analog input signal. One of the differential transconductance stages may have common mode compatibility toward the supply node at the highest potential, and the other stage may have common mode compatibility toward the supply node at the lowest potential. Furthermore, differential output currents of the transconductance input stages may be summed differentially on first and second input nodes of a differential converter stage, which converts the differential current signals to an amplified differential voltage output signal.
