Abstract:
1. A semiconductor integrated circuit device comprising: a first charging circuit connected between a first power supply and a first node and configured to charge the first node based on a first signal and a second signal generated by delaying and inverting the first signal; a second charging circuit connected between the first power supply and a second node and configured to charge the second node based on the first signal and the second signal; a first discharging path connected between the first node and a third node, and including a first switching circuit configured to be turned on and off according to the first signal, and a second switching circuit connected in series to the first switching circuit and configured to be turned on and off according to a fifth signal obtained by an operation of a third signal and a fourth signal; a second discharging path connected between the second node and the third node, and including a third switching circuit configured to be turned on and off according to the first signal and a fourth switching circuit connected in series to the third switching circuit and configured to be turned on and off according to a sixth signal generated by inverting the third signal; and a fifth switching circuit connected between the third node and a second power supply and configured to be turned on and off according to the second signal.
