We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...

This paper presents a dual-band power amplifier (PA) using a meandered line bandstop filter (BSF). An important challenge addressed in this design is to achieve proper isolation between the ...

While this op amp may actually have some utility, it is intended mainly as an educational exercise. I guarantee that if you build and experiment with this circuit, you will learn and appreciate what ...

The move to push semiconductor manufacturing processes to ever smaller dimensions continues with undiminished enthusiasm, even though progress may not be as quick as some in the industry have been ...

Important efficiency requirements exist on both the handset and the base-station sides of the telecom world. In handsets, efficiency directly translates into battery life. By increasing cell-phone ...

Sometimes I wish FETs had become practical before bipolar transistors. A FET is a lot more like a tube and amplifies voltages. Bipolar transistors amplify current and that makes them a bit harder to ...
