ABSTRACT:
A deglitch circuit capable of removing noise with low power consumption. Voltage is input to a first inverter, connected to a power supply line via a first current source and grounded via a second current source. The first inverter is grounded via a capacitor and connected to first and second transistors. The gate terminals of these transistors receive a second control voltage, which is lower than the power supply voltage, and a first control voltage, which is higher than the ground level. The second transistor is connected to the ground line via a fourth current source. First voltage is supplied to a first input terminal of the latch circuit via a second inverter. The first transistor is connected to the power supply line via a third current source. Second voltage is supplied to a second input terminal of the latch circuit via the second inverter.
