0 To 12V, 1A Variable Power Supply Circuit

This 0- to 12-Vdc variable power supply uses an IC voltage regulator and a heavy-duty transformer to provide a reliable dc power supply. Looking at the schematic shown, you can sec that transformer Tl has a 120-V primary and a 28-V secondary. Filtered dc is fed to the input (pin 2) of the LM317T...

Complementary lighting control

This lighting-control unit will fade out one lamp while simultaneously increasing the light output of another. The two loads track each other accurately without adjustments. The gate of SCRl, a silicon-controlied rectifier, is driven from a standard phase-control circuit, based, for example, on a...

Programmable bandpass using twin-t bridge

The circuit gives a programmable bandpass where both the cut-over frequency and the gain, A, are controlled independently. In the twin-T bridge the resistors R and R/2 are replaced by two double FETs, 430, the channel resistance of the first one in the series, the channel resistances of the...

7805 Turn-On Circuit Circuit

A logic level can control a 7805 regulator with this circuit. Q2 is a series switcliing transistor controlled by Ql.

Offset controlled stereo amplifier circuit

This stereo amplifier use the NE5517/A and has an excellent tracking of 0.3 dB typical easy. With the potentiometer, Rp, the offset can be adjusted.

High-Voltage Supply Circuit

This circuit uses a transistor oscillator and a voltage multiplier to charge CIO and CI 1 to a high voltage. When the spark gap breaks down, T2 produces a high-voltage pulse via the capacitance discharge of CIO and Cll into its primary.

Ammeter with six decade range II

The Ammeter measures currents from 100 pA to 100 µ without the use of expensive high value resistors.

Harmonic generator

This circuit will produce 50µV harmonics through 1296 MHz with an input of 05-1 V from a 100 or 1000 kHz crystal oscillator
