1) Consider the circuit in Figure 1. A led lamb including series-connected LEDS is wanted to be
driven with a cascode current source having a bias current of 20 mA. The circuit parameters
are as follows; (WIL)(W/L)-50/0,18, Von- 24 V, Cas = 200 uA/V, Vm =0.4 V.

a) Neglecting channel-length modulation, choose the values of R. R: and R; to place both the
transistor 0.5V away from the triode region while Ri + R2 + R: draws no more than 0,4 mA
from the supply.

b) What is the maximum number of 2V-LEDS that can be connected between Vo and node X while the cascode current source
still operates with the condition stated in a)?
c) What is the Thevenin smal signal cquivalent resistance that is seen from the terminals of the led lamb? (i, = 1, =0 i v.)
