CONSTITUTION:When a sinusoidal input signal voltage of a maximum amplitude is impressed to an input terminal IN, since a current IO flows to the common emitter of the TRs Q1, Q2 from the constant current source IO, a collector current as shown in figure flows to the TRQ2. Although a DC...
In another embodiment the voltage amplifier has a common emitter (CE) gain stage, a common base (CB) cascade stage directly-coupled to the CE gain stage, and a constant current mirror source. The integrated inductor has two inductors, each connected to one input of the amplifier input signal...
Question: Design a common emitter amplifier with a voltage gain |Av|=25. You are provided with (i) a single power supply of 10V and (b) BJTs with a de current gain of 150 . No resistor greater than 100kΩ is to be...
A transistorized voltage-controlled variable-gain audio amplifier including a transistor connected as a common-emitter amplifier, and a control circuit coupled to the emitter of the amplifying transistor and operative in response to a direct control signal to vary the impedance at the emitter without...

VOLTAGE-CONTROLLED VARIABLE GAIN AMPLIFIER
In the CE (common emitter) amplifier composed of NPN transistor, when the input signal is a sinusoidal waveform of 1 kHz and 5 mV, the output voltage waveform has a distortion of bottom flattening. This distortion is ( ). A、saturation distortion ...
“controlled cascade” circuit; this is basically a grounded-base transistor to which has been added another device which removes some of the signal from the emitter. This alters the gain of the cascade, from almost unity (whennocurrent is removed) to zero (whenallthe signal is removed.) ...
When the open-loop amplifier is within its specified IVR, the differential input signal (VIN+ –VIN–) is 180 degrees out of phase with VDIFF. When connected as a unity-gain buffer, as shown, if the common-mode voltage at VIN+ exceeds the amplifier’s IVR, J1’s gate-drain w...
2) differentaial-mode gain 差模电压放大倍数3) voltage gain 电压放大倍数 1. Most of the electronics textbooks think that the change of transistor parameter current amplification factor β can cause little change of voltage gain in one-stage common emitter configuration amplifiers. 一般电子技术...
