The differential amplifier shown in Fig. 7.14 has a differential voltage gain of 2500 and a CMRR of 30,000. A single-ended input signal of 500 μV r.m.s. is applied. At the same time, 1V, 50 Hz interference signal appears on both inputs as a result of radiated pick-up from the a.c. power system.
(i) Determine the common-mode gain.
(ii) Express the CMRR in dB.
(iii) Determine the r.m.s. output signal.
(iv) Determine the r.m.s. interference voltage on the output.
