Complementary MOSFET Common Source Power Amplifier: Advantages of MOSFETs: Complementary MOSFET Common Source Power Amplifier have several advantages over power BJTs for large signal amplifier applications. One of the most…
Power Supply Decoupling: Power Supply Decoupling - High-power amplifiers require high supply current levels, so unregulated power supplies are often employed to avoid the power wasted in a series regulator.…
Darlington Connected Output Transistors: High-power transistors usually have low current gains, so relatively large base currents must flow into Q2 and Q3 to supply a high load current. This means…
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…
IC Controller for Switching Regulators: The functional block diagram of a MC34063 integrated circuit controller is shown in Fig. 17-38. This IC is designed to be used as a variable…
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…
Op Amp Voltage Regulators: Voltage Follower Regulator - Refer once again to the Op Amp Voltage Regulators circuit in Fig. 17-11. The complete error amplifier has two input terminals at…
Improving Regulator Performance: Error Amplifier Gain - The performance of a regulator is dependent on the voltage gain of the error amplifier. A higher gain amplifier gives better line and…
