ULTRA_HIGH_GAIN_AUDIO_AMPLIFIER

Published:2009/6/24 3:33:00 Author:May

ULTRA_HIGH_GAIN_AUDIO_AMPLIFIER
Sometimes called the JFET μt-amp, this circuit provides a very low power, high gain amplifying function. Since pt of a JFET in-creases as drain current decreases, the lower drain current is, the more gain you get. Input dynamic range is sacrificed with increasing gain, however.   (View)

ELECTRONIC_BALANCED_INPUT_MICROPHONE_AMPLIFIER

Published:2009/6/24 3:30:00 Author:May

ELECTRONIC_BALANCED_INPUT_MICROPHONE_AMPLIFIER
It is possible to simulate the balanced per-formance of a transformer electronically with a different amplifier. By adjusting the presets, the resistor ratio can be balanced so that the best CMRR is obtained. It is possible to get a better CMRR than from a transformer. Use a RC4136 which is a quad low noise op amp.   (View)

GENERAL_PURPOSE_PREAMPLIFIER

GENERAL_PURPOSE_PREAMPLIFIER
Not much can be said about how the LM382 works as most of the circuitry is contained within the IC. Most of the frequency-determining components are on the chip-only the capacitors are mounted externally. The LM382 has the convenient characteristic of rejecting ripple on the supply line by about 100 dB, thus greatly reducing the quality requirment for the power supply.   (View)

RADON_MONITOR_AMPLIFIER_AND_HEAD

A positively charged anode wire attracts electrons and a negatively charged cathode attracts positively charged ions. The recombination of electrons and ions causes a current that produces a voltage pulse. The cathode is maintained at -500 V by a charge on the 0.1-μF capacitor.A beverage can forms the chamber, an aluminum can forms the cathode, and half cans form protective end covers. The amplifier circuit board is shown to the left of center.   (View)
