One of my first jobs as a freshly minted graduate engineer involved the maintenance of a set of analogue chart recorders. They were museum pieces by the early 1990s: a motorized roll of graph paper ...

Transistor Amplifiers, Dennis Feucht, Innovatia, 2016, ISBN: 9781682736265; $60 US. Transistor amplifier literature has existed for well over a half century. Why another book on an old subject? What ...

A research group succeeded in developing the world's thinnest and lightest differential amplifier for bioinstrumentation. Conventionally, bioinstrumentation circuits for health care and medical use ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...

PMOS transistors are less vulnerable to substrate noise since they’re placed in separate wells; designers implement guard rings to attenuate the substrate noise propagation. However, substrate noise ...

Current feedback amplifiers are one of the oldest amplifier topologies around. I remember the days when Comlinear ruled the market in the 80s with their high speed offerings. Analog Devices, ...

Current differencing transconductance amplifiers (CDTAs) provide a versatile platform for signal processing in contemporary integrated circuits. By converting differential input currents into ...

The research group in this study developed the world’s thinnest and lightest signal amplifier for bioinstrumentation and demonstrated high-precision monitoring of electrocardiac signals with reduced ...
