Differential Amplifier Circuit

Published:2011/5/3 1:57:00 Author:Felicity | Keyword: Differential Amplifier Circuit,

The way of differential connection: the input signal of differential amplifier circuit is inputed from integrated operational amplifier's phase and RP. If the feedback resistanceRF equals to the input resistance, in-phase input voltage minus phase input voltage is the the output voltage. This circuit is also called subtraction circuit.   (View)

High input impedance broadband amplifier circuit diagram composed of field effect pair transistor

Published:2011/5/2 22:46:00 Author:Nicole | Keyword: impedance, broadband, amplifier, field effect, pair transistor

The figure 1 is as shown, it is a high input impedance broadband amplifier which is composed of field effect pair transistor. In the circuit, field effect pair transistor VT1 is connected to VT2, VT2 is as constant current source, UGS's drift of VT1 is decided by R1, then the input is equal to output voltage, the single terminal output is added to the differential amplifier TA7031. Compared this circuit's frequency characteristic to TA7031's frequency characteristic, it is dropped less than 1dB nearby lOMHz, the maximum output voltage is 3V. C1 is feedforward compensation capacitance.   (View)
