19. you have a physiological signal (represented as a sinusoid signal) with amplitude of 150 mV, frequency of 20 Hz, and a dc offset of 1.5 V. (15 pts) 1) Design a one-op-amp differential amplifier with gain of 10 to amplify the signal and remove the dc offset. (hint you can draw the circuit on a piece of paper in addition to your Wilspice model for this question. Provide the specific values for the input voltage signals and resistors you use). 2) Use LTspice, simulation to determine the common-mode gain if the value of resistor R2 in Figure E1.11(a) changes by 5%. (hint: the common-mode gain is the ratio between the offset input voltage and the offset output voltage).
