Abstract: Systems and methods disclosed herein provide for an improved glitch-free clock multiplexer exhibiting noise insensitivity with reduced power consumption and reduced physical area on a chip. The embodiments disclosed herein operate without any need of a reference clock. Due to which, clock interchangeability is possible at any point of time. An example glitch-free clock multiplexing according to the embodiments disclosed herein utilize a plurality of clock path circuits, each corresponding to a clock. The clock path circuits are activated responsive to a system startup signal. Based on a clock selection, the embodiments herein deactivate clock path circuits for unselected clocks and, dependent on the deactivation of the unselected clock path circuits, activate clock path circuits of any selected clocks.
