Question
Problem 1. [20 pts] Transistor in a special connection Given the circuit below with the following parameters: - M1: Vt,n=0.48 V, unCox 90 uA/V², W/L = 10 um/4 um, λ = 0.01 [1/V] = VDD+Vdd - Supply voltage: VDD = 3.3 V, vdd = 10 mV IDI R VO M1 a. Find the value of resistor R so that the bias current is 10uA. (Hint: Channel length modulation should be considered.) Use the resistor value in (a) for the following calculations: b. What configuration (connection) M1 is having? What region is it in? d. c. Find the transistor small-signal model parameters: gm, ro and rp1. Find the expression and value for the small-signal transfer function (gain) of vo/vdd.
