CLOCK GATING CIRCUITS AND METHODS FOR DUAL-EDGE-TRIGGERED APPLICATIONS
Abstract:
Embodiments disclosed herein relate to clock gating. An example integrated circuit includes an oscillator that outputs a clock signal to a clock gating system that generates and provides a gated clock signal to a data storage circuit. The clock gating system includes a first digital logic circuit having an input coupled to the oscillator to receive the clock signal, an active-low latch that includes an input coupled to an output of the first digital logic circuit and an input coupled to receive an enable signal, a second digital logic circuit that includes an input coupled to the oscillator and an input coupled to the output of the active-low latch, and an active-high latch that includes an input coupled to the output of the second digital logic circuit, an input coupled to receive the enable signal, and an output configured to provide a gated clock signal to the data storage circuit.
