Sequential elements with programmable feedback to program leakage in ASICs

Power dissipation of sequential static latch, implemented in CMOS, may be reduced by removing clocked elements from the circuit. One way to do this may be to replace a clocked digital feedback path with an analog programmable feedback path. An analog programmable feedback path, such as disclosed, may, for example, provide a constant, non-clocked bias by providing constant bias voltages to transistors in the feedback path such that they function as analog devices rather than digital switches. This bias may be adjusted, e.g., to reflect the circuit's operating environment.
