This is The Fet Amplifier circuit. This circuit uses FET transistor. The gate of the FET must be negative with respect to the source, so a bias can be achieved in the following manner. The voltage that is across the source resistor is developed by the drain current flowing through the source resistor. Due to that action, the emitter become […]

This is a The Directly (DC) Coupled Amplifier circuit. This circuit is built from NPN transistor and PNP transistor. This circuit is used to amplify a DC signal. Since there is no coupling capacitor to block DC, this circuit can perform as DC amplifier as well as AC amplifier. Beside that, this circuit can amplify a very low AC frequencies […]

This is a The Push Pull Power Amplifier circuit. This circuit is a class B push pull amplifier. When there is no signal input, the TR3 and TR2 are not conducting. If there is no signal input, this circuit draw a very little current. This circuit has a phase splitter that is built from T1 and TR1 which opposite polarity […]
