Altronics had a Mosfet amplifier module which produced 200W into a 4 Ohm load and so we decided to take a look it. [108] Discrete MOSFET devices are widely used in applications such as switch mode power supplies , variable-frequency drives and other power electronics. Differential Amplifier Operating in Purely Differential Input Signal: (a) Original Equivalent Circuit, (b) Reduction to Two-port Network, and (c) Changing Input Port Variable to V 1 =V id. In most of the cases n-channel MOSFETs are preferred over p-channel MOSFETs for several advantages. Introduction: A solid-state HF amplifier differs fundamentally in its design concept from a tube amplifier.
