Abstract
A switching circuit includes: an output inverter that switches an output signal between high-level and low-level voltages; a first inverter that generates the high-level voltage from a first supply voltage according to a first input signal; a second inverter that generates the low-level voltage from a second supply voltage according to a second input signal; a first bias portion that lowers the voltage fed to the high-side power terminal of the first inverter by a first bias voltage to feed the result to the low-side power terminal of the first inverter; and a second bias portion that raises the voltage fed to a low-side power terminal of the second inverter by a second bias voltage to feed the result to the high-side power terminal of the second inverter.
Claims10
A switching circuit comprising:
- an output inverter configured to switch an output signal to either a high-level voltage or a low-level voltage,
- at least one stage of a first inverter configured to generate the high-level voltage from a first supply voltage according to a first input signal,
- at least one stage of a second inverter configured to generate the low-level voltage from a second supply voltage according to a second input signal,
- at least one stage of a first bias portion configured to lower a voltage fed to a high-side power terminal of the first inverter in each stage by a first bias voltage and to feed a lowered voltage to a low-side power terminal of the first inverter in each stage;
- and
- at least one stage of a second bias portion configured to raise a voltage fed to a low-side power terminal of the second inverter in each stage by a second bias voltage and to feed a raised voltage to a high-side power terminal of the second inverter in each stage.
