Abstract:
A feedthrough signal transmission circuit includes a first permanently on cell and a cell controlling unit. The first permanently on cell is arranged to transmit a first control signal. The cell controlling unit is coupled to the first permanently on cell, and includes a power switch and a plurality o buffers. The power switch is coupled to the first permanently on cell, arranged to receive a switch control signal and the first control signal, and selectively output the first control signal according to the switch control signal. The plurality of buffers is coupled to the power switch. Each of the buffers is arranged to buffer a data input only when powered by the first control signal output from the power switch.
