The Si transistors in the differential amplifier circuit of the figure shown have negligible leakage current and ß1 = ß2 = 60.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.Analysis and Design of BJT Differential Amplifier. Abstract: A differential amplifier is a basic building block for analog integrated circuit design; the operational …

The overall single-ended to differential gain (GAIN) must take into account the input attenuation of the R S and R T resistive divider and the effect of adding R2. In this example, the overall gain of the amplifier from signal source to differential output is only 4.44 even though the amplifier has a fixed gain of 10.The differential amplifier circuit using transistors can be designed as shown in the figure below which consists of two transistors T1 and T2. These transistors and resistors are connected as shown in the circuit …Dec 8, 2017 · Here's the approach. Starting at the collector of Q 2, we can say at the voltage there is 20 V − I C 2 ⋅ R C 2. We now subtract from this V B E 3 ≈ 700 mV to get to the emitter of Q 3. Then apply the voltage divider there to get the base voltage of Q 2 as: V B 2 = ( 20 V − I C 2 ⋅ R C 2 − V B E 3) ⋅ R 5 R 4 + R 5. Build the NPN differential pair test circuit shown in figure 2. The connections to the ALM1000 are as indicated in the green boxes. Q 1 and Q 2 should be selected from your available transistors with the best matching of VBE. The emitters of Q 1 and Q 2 share a common connection with one end of R 3. The other end of R 3 is connected to ground ...Unlike normal amplifiers, which amplify a single input signal (often called single-ended amplifiers), differential amplifiers amplify the voltage difference between two input signals. Using the simplified triangle …

Here is a plot with V IN1 and the differential output voltage: Here we have an output amplitude of 10 mV and an input amplitude of 1 mV; hence, our simulated differential gain is 10. The formula for theoretical differential gain is. Adiff = gm ×RD A d i f f = g m × R D. where g m can be calculated as follows:Fig. 6.7: The basic BJT differential-pair amplifier configuration driven with the multiple-input source arrangement described in Section 6.1. Fig. 6.8: The schematic captured by LTSpice for calculating the 2-port equivalent of the differential amplifier shown in Fig. 6.7. Several Spice directives are used in this example. 2 form a BJT differential pair, as does transistors Q 4 and Q 5. The first differential pair is the input stage, where the second differential pair acts as a gain stage (recall the open-circuit voltage gain of a BJT diff. pair is large). Transistor Q 8 is clearly part of an emitter-follower output stage. ….
