Design (choose RE) the following BJT differential amplifier for a differential gain where the output is taken single-ended with common mode input (vo1/vid), so that, Adc = −1/2[gmRc] = −10 V/V. The resistance Rc = R1 = R2 = 1K. VBEon = 1 V and β = 100. Find the differential gain Ad and the dB CMRR (Adc/Ad). Assume V1=V2 =0V.

A differential amplifier with a single-ended output is shown below along with the MOSFET parameters. The amplifier is to be designed for a differential mode gain of 10 and a CMRR of 200 . The current source I must have a voltage drop VCS ≥ 1 volt. The voltage V0 = 0 when the MOSFET gates are at ground potential (Va = Vb = 0). Assume the current source I must have a voltage drop of at least Vcs, min = 1 V. MOSFET Parameters kn = 2×10−4 A/V2 Vt = 1 V;VA = 30 V a. Show that the single-ended differential gain can be expressed as Ad = gmro||RD/2 = Ad = kn I VDD(1 + VDD/VA). Hint: Express gm, RD, and ro as functions of the drain current 1 /2. b.

The differential amplifier of Figure 2 uses BJTs with β = 100. Identify and sketch the differential and common-mode equivalent half circuits. Determine the differential and common-mode input resistances. Assuming the output is taken single-endedly (as shown), determine the differential and common-mode voltage gains and the CMRR. Figure 2
