| A fundamental property for the first microwave amplifier in a radio receiver is its noise figure. This is normally given in decibel (dB). A...

| Decent potentiometers for setting the volume in amplifiers are still quite expensive. However, there is a cheaper alternative, and it’s bett...

| The signal from a microphone is two weak for a standard line input. This low-noise DC-coupled microphone amplifier provides a solution for a...

| This preamplifier was designed for low-impedance signal sources like MC (moving-coil) pick-up cartridges used in highend record players...

| The MGA-86563 from HewlettPackard is a three-stage, GaAs, MMIC (monolithic microwave integrated circuit) that offers low noise figure an...

| Amateur television (ATV) is among the most popular, technically advanced and exciting sub-activities available to the licenced radio am...

| With the arrival of matched transistors in a single package it seems that the quest for the zero-noise microphone preamplifier has receive...

| One way of desigining a low-noise amplifier is the shunting of several input stages. This reduces the overall noise, Un=U(i)n-1/2, where...

| Opamp TypeSSM2017 from PMl is eminently suitable for designing a very-Iow-noise microphone preamplifier.

| This design goes to show that low noise and substantial amplification can go hand in hand in a single amplifier with excellent wideband ch...
