Question 1. Figure I shows a PMOS based current mirror where V4-5V, K-240 HA/V, Vy-0.6 V, Irer = 50 uA and assume 1 -0.01 V. The (W/L) for the two MOSFETS are shown as (10/1) and (20/1) for M and M2 respectively. (a) Find the value of Vs for the two mosfets. You may ignore early effect while calculating (20 marks) Vs (b) Find the mirror ratio MR Tour / IRF (25 marks) (c) Find the value of output current (5 marks) 2. Figure 2 shows the same PMOS current mirror as in Figure 1 but with an extra resistor R -90 kn added between the gate node and Vd. Rest of the parameters are same as question 1. (a) Find the value of Vs for the two mosfets. You may ignore early effect while calculating VSG (35 marks) (b) Find the mirror ratio MR-low/ REF (10 marks) (c) Find the value of output current om (5 marks) MLL (10/1) 0/1) Tref = 50uA 0 GND-OV = GND-OV = Figure 1 V DD M2 (10/1) (20/1) IREF = 50ºA (D) GND=OV = GND=OV = Figure 2
