DIY High Power Amplifier Very Simple Using 20 Transistors
WebJul 2, 2012 · The bottom mosfet is the amplifier and would show a dynamic impedance related to both Cgs and Cgd. This would require a much lower driver impedance to properly handle this load. The 4mA of current (1/2 of the tail current from input differential) would not be enough to handle this dynamic load. WebMay 5, 2024 · The circuit relies upon the a couple of series hooked up MOSFETs, T15 and T16., actually being powered in anti-phase by a differential amplifier. Given that the input resistance of MOSFETs is of the level of 10 ohms, the drive electrical power really needs to be simply modest. The MOSFETs are as a result voltage- operated. ron henrey solvang
