There is no mechanism to handle asynchronous signals in that implementation. This leads to … See more Figure 1 shows a simple implementation of a clock switch, using an AND-OR type multiplexer logic. The multiplexer (MUX) has one control signal, named SELECT, which either propagates CLK0 to the output when set to … See more A solution to prevent glitch at the output of a clock switch where source clocks are multiples of each other is presented in Figure 2. A negative … See more At chip startup time, both flip flops DFF0 and DFF1 should be reset to the “zero” state so that neither one of the clocks is propagated initially. By starting both flip flops in “zero” state, fault tolerance is built into the clock switch. … See more
WebGlitch free clock mux; Constraining Logically Exclusive Clocks in Synthesis. This is article-5 of how to define Synthesis timing constraint. Logically exclusive clocks are active in the design but cannot interact with each other. When dealing with logically exclusive clock, one often sees a mux with the select line determining which clock is ... Web8. The clock switching circuit of claim 7, wherein the first enable is logic high at reset. 9. The clock switching circuit of claim 1, wherein the priority multiplexer is configured to block a glitch at the logic gate output. 10.

In this paper, we propose an on-chip clock controller architecture to detect automatically clock failure and to switch the safe backup clock. The implemented edge detector (ED) unit identifies the abnormal low-frequency status of the clock source.
WebOct 17, 2024 · In this study, we describe a dual-chopper glitch-reduction current-feedback instrumentation amplifier (CFIA) with a ripple reduction loop. The amplifier employs the chopping technique to reduce low-frequency noise, such as 1/f noise. A glitch caused by chopping occurs at each chopper clock edge and results in intermodulation distortion …
