| Paired with an effective directional antenna, a high-performance, two-stage antenna amplifier designed for the VHF FM broadcast band can hel...

| The current surge demanded at power-on by a circuit presenting a large capacitive load to the power supply can destroy the power supply or t...

| Analog circuits have had their day; everything is digital now. Here we present a simple digital amplifier built with standard CMOS logic gat...

| The OP284 is a low noise dual op amp with a bandwidth of 4 MHz and rail-to-rail input/output operation. These properties make it ideal for...

| The video amplifier in the diagram is a well-known design. Simple, yet very useful, were it not for the ease with which the transistors...

| The U2514B is an integrated bipolar radio circuit suitable for digital tuning systems. It contains an FM front end with preamplifier a...

| As we have seen in Part 2, the SPICE primitives, such as resistors, capacitors and voltage sources, are defined in a netlist by an appropria...

| The matching circuit consists of a variable passive attenuator and an amplifier with variable gain: 0-20 dB. The attenuator reduces the s...

| On much audio equipment, the headphone output is simply derived from the loudspeaker output via a series resistor: not a very elegant desi...
