Abstract
PURPOSE:To reject the switching distortion, by providing the clamp voltage circuit in which the bias voltage is fluctuated with the voltage at the middle point of output at all times and turning on and off the switching element with the bias voltage. CONSTITUTION:When the input signal is positive half cycle, the diode 15 and transistors Tr3, 5 are conducted and the voltage is produced across the emitter resistor 9 to supply the current to the load 11. Further, the bias circuit 2 is operated to cut off Tr4, 6. But, since the voltage of the outputs a, b of the clamp circuit 14 is always following to the voltage at the middle point o, the bias voltage is not changed with Tr4, 6 to block to cut off Tr4, 6. At the negative half cycle of input signal, entirely converse operation is made. As a result, the waveform of current flowing to Tr5, 6 is shifted from the zero point by the bias current with the circuit 14 to prevent the production of switching distortion.
