摘要： A method of reducing power consumption caused by leakage current in an interface circuit between modules that are driven by different power sources is disclosed. The interface circuit includes an output driver that operates by a first power supply voltage in a first mode and does not operate in a second mode in which the first power supply voltage is prevented from being applied, an input buffer that is operated by a second power supply voltage in the first and second modes, and a transmission line that connects an output terminal of the output driver to an input terminal of the input buffer. The interface circuit further includes a current leakage prevention circuit that prevents, in the second mode, a current leakage in the input buffer between a second power supply voltage source that supplies the second power supply voltage and a ground voltage source.

摘要： An AB class buffer amplifier controls quiescent current. The AB class buffer amplifier includes a first current controller and a second current controller. The first current controller sources current to an output node in response to a first logic level of a first signal, and buffers and outputs an input voltage to the output node in response to a second logic level of the first signal. The second current controller sinks the current from the output node in response to a second logic level of a second signal, and buffers and outputs the input voltage to the output node in response to a first logic level of the second signal. The first and second signals are generated at the first logic levels if the input voltage is higher than the output voltage and at the second logic level if the input voltage is lower than the output voltage. The AB class buffer amplifier may further include comparing unit which compares the input voltage with an output voltage from the output node and generates the first and second signals in response to the compared results. The comparing unit includes first and second comparators. Accordingly, the AB class buffer amplifier can drive an external circuit using high currents by freely controlling the amount of quiescent current, and easily sourcing and sinking quiescent current flowing to an output node of the amplifier.
