PURPOSE:To change a voltage of a connecting point between a pair of diodes and load elements and to attain a circuit made possible for high speed operation, by providing with the diodes, controlling current switching elements and flowing a current to either one of the diodes. CONSTITUTION:As the initial conditions, a clock pulse 10a is at a level higher than the level of a clock pulse 10b, a transistor (TR) 9a of a current switch turns on and a TR9b turns off, and a current flows to TR couples 7a, 7b forming a differential amplifier. An output voltage produced across load resistors 4a, 4b is changed in response to an input voltage in this case. When the pulse 10b goes to a high level, the current switch is changed over, the TR9b turns on and the TR9a turns off, the differential amplifier is stopped, the diodes 1a, 1b start the opeation, and the output voltage is reset to zero. The conventional amplifier circuit is operated near this state normally, it is most preferable as the reset state and the response speed is faster by several times. |
