1. Assume Vx= (1.5+ 0.01sin 2nft) V, where f= 10 kHz and R₁ = 5kQ. (a) Determine the operating point of D₁ (both current and voltage, use exponential model, where Is 10-¹7A). (b) Use small-signal analysis to determine VD (t) (the total voltage across D1, including both AC and DC). Plot VD1(t) as a function of time. Ix Vx + R₁ MMD D₁
