Unformatted text preview: 5. Frequency Response [20 points] Consider the amplifier shown below. Assume gmo = 5 m8, gm12 = 1 m8, gm3,4 = 2 m8, r00 = 50 k0, r012 = 100 k0, and ram = 200 k0. (Note: These are not the correct values for problem 4.. .) Neglect the body effect and assume that all transistors are in saturation. Remember that the inputs are a superposition of the common- mode and differential-mode components, namely Vin+ = VCM + Von/2 and Vin- = VCM — Von/2. a) For the differential-mode half-circuit, calculate the gain (Ad = VOJVin+). b) For the common-mode half-circuit, calculate the gain (Ac = Vo—Nim). c) If a resistor, RL, is added between Vo+ and Vo-, what effect does this have on Ad and Ac? Answer gualitatively in one or two sentences. d) If a capacitor, 033, is added between V9.) and Via", what effect does this have on Ad and Ac? Answer gualitatively in one or two sentences. e) For the common-mode half-circuit only, 055 contributes to fi-i. Calculate the time constant for 059 = 100 pF. ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
