4. The circuit below is called the instrumentation amplifier. (Hint: Refer to section 2.4.2 in the Sedra/Smith book) a) The instrumentation amplifier cascaded non-inverting amplifiers with a differential amplifier. Explain why this is done. b) Design this instrumentation amplifier circuit to realize a differential Gain Ad, variable in the range of 2-50, utilizing a 100-k potentiometer(pot) as a variable resistor. (Hint: design here means to select all resistor values to obtain this function, multiple solutions are possible) O A₁ RA R₁ R3 w w 2R R₁ A3 w + ° w R₁₂ RA A2 리고 다 =
