Q1 [55 marks] In Fig. 1 below assume the source voltage is u(t)=300sin(5000x) and R-7.592. The switch is to be controlled by the control circuit (Ctr Cir) which can produce a maximum current of 1A and voltage pulses with amplitude that changes between 0 and 5V. Assume that you have the choice to implement the circuit with BJT or a MOSFET transistors. The BJTS transistors have collector current rating of 45A, the de current gain ß-5 and the on-voltage is 2V; and the MOSFET transistors has drain current rating of 25 A, the on-voltage drop is 2V and the threshold voltage is 2V. vs(t) R www Ctr Cir Vetr Io Fig. 1: the circuit of Q1.
