| 摘要 |
<p>The present invention relates to a VMDC power amplifier which has a muting function by using the heater delay property of a triode, and improves linearity in operating the constant current of the triode. It includes a first amplification terminal which amplifies an input signal according to a via voltage; a second amplification terminal which receives the output of the first amplification terminal with a bias voltage and controls a load current; an output trans which is connected to the second amplification terminal and outputs the input signal with an amplified signal; and a bias voltage control part which supplies the output current of the second amplification terminal to the first amplification terminal with a bias voltage.</p> |
