Abstract
A soft latch circuit having a first and second inverter is disclosed. The output of the first inverter is connected to the input of the second inverter, and the output of the second inverter is connected to the input of the first inverter. The first inverter includes a complimentary pair of field-effect transistors (FETs). The second inverter includes either a complimentary pair of current mirrors, or a current mirror and a complimentary FET, the latter providing improved noise immunity characteristics when the soft latch is set in only one direction.
