Step 3.1 - Set the capacitive charge of the phono preamp
The laser unit includes an oscillator unit, a preamplifier unit and an amplifier unit.
Said optical receiving module comprises a photoelectric conversion unit and a preamplifier unit.
The signal of said photoelectric conversion unit is output to said preamplifier unit.
Said preamplifier unit is a trans-impedance amplifier, and feedback resistance unit is connected to the input and output end of the amplifier.
A variable gain, low noise amplifier is described, which is suitable as the input amplifier for a wireless terminal, or as the pre-amplifier stage of a wireless terminal transmitter.
When receiving, the floating unit restores the bias potential of the preamp, and the preamp is used as an ordinary receiving preamp.
A pre-amplifer is present and is one of the components of the electrometer.
The end-amplifier (16) is connected to the pre-amplifier (15).
