Abstract:
The disclosure relates to a latch including a first inverter with a first pair of field effect transistors (FETs) configured with a first channel width to length ratio (W/L), and a second inverter with a second pair of FETs configured with a second W/L different than the first W/L. Another latch includes first and second inverters; a first negative feedback circuit including first and second FETs coupled between first and second voltage rails, the input of the first inverter coupled between the first and second FETs, and the first and second FETs including gates coupled to an output of the first inverter; and a second negative feedback circuit including third and fourth FETs coupled between the first and second voltage rails, the input of the second inverter coupled between the third and fourth FETs, and the third and fourth FETs including gates coupled to an output of the second inverter.
