Title: Voltage comparator
Inventor: MUTO SHINICHIRO
IPC: H03K5/08
Filed: 1991-12-03
Abstract: PURPOSE:To obtain a voltage comparator which performs a stable operation even when a source voltage goes down to a low voltage by defining the potential of an output terminal when no operation is performed at source potential, and suppressing the malfunction of a logic circuit connected to the next stage. CONSTITUTION:When the potential V1, V2 of input terminals T1, T2 show low potential, an NMOSFET M6 functioning as a switch is de-energized by setting a control terminal C1 at low potential when no operation is performed. When the potential V1, V2 of the input terminals T1, T2 in no operation show the low potential, PMOSFETs M1, M3 (driver) are energized, and the potential of an output terminal TOUT is fixed at the potential of a high potential source voltage Vdd. In such a way, the voltage comparator connects the source of a MOSFET for driver directly to the power source by setting a current mirror circuit as a load and a MOSFET whose conduction type is different from that of the load as the driver. Thereby, the output potential can be defined at the same potential as Vdd even when no operation is performed.
