Transformer Coupled Class B Amplifier: Class B Amplifier - The inefficiency of Class-A amplifiers is largely due to the transistor bias conditions. In a Class-B amplifier, the transistors are biased…
Transformer Coupled Class A Amplifier: Class A Circuit - Instead of capacitor coupling, a Transformer Coupled Class A Amplifier may be used to ac couple amplifier stages while providing dc…
Step Down Converter: A step-down switching regulator, or Step Down Converter (also termed a buck converter), produces a dc output voltage lower than its input voltage. The basic circuit arrangement…
Hartley Oscillators using Op-Amp: Hartley Oscillators using Op-Amp circuit is similar to the Colpitts oscillator, except that the feedback network consists of two inductors and a capacitor instead of two…
Colpitts Oscillator using Op Amp: The Colpitts Oscillator using Op Amp circuit show in Fig. 16-4 is similar to the op-amp phase shift oscillator, except that an LC network is…
Two Diode Full Wave Rectifier Circuit: The Fig. 3-2 shows the Two Diode Full Wave Rectifier Circuit, and its input voltage is supplied from a transformer (T1) with a center-tapped…
