ABSTRACT:
A noise filter circuit includes a latch circuit that receives an input signal. The latch circuit includes first and second logic circuits (e.g., NAND circuits). The first and second NAND circuits are configured so that the capability of a P-type transistor that receives a set signal or a reset signal is lower than the capability of an N-type transistor that receives the set signal or the reset signal and the capability of an N-type transistor connected in series with the N-type transistor that receives the set signal or the reset signal (total capability). The noise filter circuit may include a waveform adjusting circuit that receives an output signal from the latch circuit.
