You need a TVS diode because many voltage regulators do not have the ability to sink current, nor can they respond fast ...

Ultra-low noise discrete microphone/line preamplifier with hand-selected 12AX7 tube for ultra-musical sound Mic input stage based on discrete, conjugate transistor pair circuitry Ultra-wide ...

A new low-noise amplifier (LNA) aims to bolster positioning performance and lower current consumption for a wide range of applications such as active antennas, car navigation, dashboard cameras, and ...

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct?

As for the amp portion of the device, the Serenade Wireless uses a Class A circuit based on a fully discrete transistor amplifier. Using a 50W toroidal transformer, it keeps things extremely quiet. In ...

We connect every turntable to the same lab reference speakers via a preamp, so all are tested under an identical setup. For turntables that have built-in speakers, we test them both in this setup and ...
