BJT Differential Pair Amplifier with BJT Current Mirror
Differential BJT amplifier 1. Introduction The differential amplifier has two input signal sources. The ideal differential amplifier produces an output voltage that is the difference between the two input voltages. Vout = Avd(Vin1-Vin2) The differential amplifier has two single ended output voltages. Vout1 (inverting output) Vout2 (non-

A single BJT differential pair is shown below. For RL1 and RL2 =1 k , calculate IBIAS to set VO1 and VO2 at a level that will give the maximum output swing. Assume VCEsat =0.2 V and VBE = 0.7 V. With your value of IBIAS calculate the differential mode gain Adm = vout/vin and the common mode gain Acm=vout/vin. What is the CMRR? FIGURE 1.

The objective of this activity is to investigate a simple differential amplifier using NPN transistors. First, we need to make a few notes on hardware limitation issues. The waveform generator in the ADALM2000 system has a high output bandwidth and with that high bandwidth comes wideband noise.

7.3 The BJT Differential Pair
BJT Differential Pair Osc A BJT version of the oscillator has limited voltage swing determined by the differential pair non-linearity. We can increase the voltage swing by emitter degeneration. A more popular alternative is to provide feedback capacitors. The negative conductance is decreased by the feedback factor.

BJT Differential Pairs Now lets consider the case where each input of the differential pair consists of an identical DC bias term V B, and also an AC small-signal component (i.e., v 1(t) and v 2(t)) CC As a result, the open-circuit output voltages will likewise have a DC and small-signal component.

The differential amplifier can be implemented with BJTs or MOSFETs. A differential amplifier multiplies the voltage difference between two inputs (Vin+ - Vin-) by some constant factor Ad, the differential gain. It may have either one output or a pair of outputs where the signal of interest is the voltage difference between the two outputs.

It refers to the gain of the transistor, collector current divided by base current. You can consider the 1 mA evenly distributed as a first order approximation. In reality, this only happens right at the cusp where the differential pair is in balance.
