A class-F/inverse class-F load circuit design method that includes parasitic elements such as drain-source capacitance and bonding wire inductance has been developed. For the class-F load circuit ...

This paper presents a modified parallel-circuit class-E amplifier that accommodates devices with larger output capacitances, recovering the class-E operating conditions. The finite inductor in the ...

In a Class A circuit the level of that current is always set to maximum. If that amplifier design is working at full volume then the bulk of that energy is used to drive the speakers. (Note that no ...

Moreover, the CDBA can be operated in either voltage or current mode, which provides a significant range of flexibility for circuit designers. Figure 1 Here is a symbolic representation of the current ...

Featuring many of the same attributes as its Method 3 monoblock amplifier, the new Method 6 (SRP: $20,000) offers Infigo Audio’s “no shortcuts” approach to product design. Like its predecessor, Method ...

The amplifier resonant tank circuit must be tuned to the operating frequency and primary-side coil inductance to ensure consistent oscillation and maximum power transfer. Fig 1: The functional block ...

As we’ve followed a trail through Hi-Fi and audio systems from the listener’s ear towards the music source, we’ve reached the amplifier. In our previous article we gave a first in… ...

A shortwave transmitter can be built with IC CD4049, which is used as an oscillator and a buffer amplifier. The transmitter can be crystal controlled to work at a frequency of 3MHz to 5MHz, which ...

Class B Amplifier Class B amplifier is the actual Push-Pull Amplifier. Efficiency of Class B amplifier is higher than Class A amplifier, as it consists of two transistors NPN and PNP. The Class B ...
