VOLTAGE-CONTROLLED POWER AMPLIFIERPROBLEM TO BE SOLVED: To enable a drain voltage control following the envelope of an input signal at a radio frequency in a voltage-controlled power amplifier for amplifying the input signal.OISHI YASUYUKI大石 泰之...
Many car audio amplifiers have what is called an unregulated power supply. The power supply is what converts the vehicle's charging voltage into power that the amplifier can use. And if the power supply is an unregulated design a boost in voltage from the vehicle means a boost in power fro...
