Name Problem 3. [10 pts] Current Mirror VDD M3 IDI M1 TOUA ID2 HCM4 Ips Rp2 M2 Ro Given the circuits on the left. Ignore the channel length modulation. Assume these

transistors are fabricated on the same technology such that all NMOS transistors have the same Vt,n and μn, and all PMOS transistors have the same Vt,p and up. Prove that if all transistors are in saturation, the following ECE 102 - HW5 relationships between the transistor currents are true: D² = (W/L)₂ ID₁ (W/L)₁ and ID4 (W/L)4 ID3 (W/L)3
