Abstract:
An oscillating circuit comprising:a first terminal;a second terminal;a gate circuit coupled between a first electrical source and a second electrical source, the gate circuit having a first input terminal receiving a signal supplied to the first terminal, a second input terminal receiving a standby signal and an output terminal, the gate circuit outputting an oscillating signal from the output terminal in response to the signal supplied to the first terminal when the standby signal has a first level, the gate circuit not outputting the oscillating signal from the output terminal when the standby signal has a second level;a switch circuit having a first node coupled to the output terminal of the gate circuit and the second terminal and a second node coupled to the first terminal, the switch circuit electrically connecting the first terminal and the second terminal when the standby signal has the first level, the switch circuit electrically disconnecting the first terminal and the second terminal when the standby signal has the second level; andan output circuit outputting a signal in response to a signal output from the output terminal of the gate circuit.
