See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...

[Alan’s] friend came to him with a problem. He loved listening to his scanner, but hated the volume differences between stations. Some transmitters would be very low volume, others would nearly blow ...

At the IEEE International Solid State Circuits Conference 2005 in San Francisco (February 6 – 10, 2005) Infineon Technologies AG held several technical lectures presenting trend-setting results from ...

ISSCC, the International Solid-state circuits conference, is the IEEE’s annual showcase for all that is best in on-chip circuit design from across the globe. Thousands of engineers will flock there ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

Supertex introduces the MD7120, a high voltage, high speed, N-channel, full-bridge power MOSFET driver for use in Class-D audio amplifiers. Supertex, a specialist in high voltage analogue and mixed ...

Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications in a world where electronics are becoming more pervasive. Finding materials ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.
