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 ...

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 ...

A few summers of my misspent youth found me working at an outdoor concert venue on the local crew. The local crew helps the show’s technicians — don’t call them roadies; they hate that — put up the ...

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 ...

Negative group delay circuits represent an innovative frontier in electronic engineering, wherein the output signal appears to precede its input. This seemingly paradoxical behaviour is achieved ...

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.
