ANALOG MINIMUM OR MAXIMUM VOLTAGE SELECTOR CIRCUIT

摘要

A circuit includes multiple input sub-circuits coupled to a common output node. Each input sub-circuit includes a transconductance cell. A diode is coupled between the output of the transconductance cell and a common output node. A feedback circuit is coupled between the common output node and a second input of the transconductance cell. A voltage follower is coupled between the common output node and a reference voltage, with an input coupled to the output of the transconductance cell.
