Assignment1: Advanced Analog Mixed Signal Design MEL ZG 625
1. For the CMOS operational amplifier shown in calculate the open–loop voltage gain, unity gain bandwidth, and slew rate.
Assume that the gate of M9 is connected to the positive power supply and that the W/L of M9 has been chosen to cancel the right half–plane zero. [6] Show your results with a SPICE simulation. Assume that Kn= 60.4μA/V2 Kp= 30.2μA/V2 . Leff= L–2Ld– Xd where Ld= 0.3μm & Xd= 1μm 𝜆𝑛 × 𝐿 = 0.2μm/V, 𝜆𝑝 × 𝐿 = 0.1μm/V Now using this develop a fully differential amplifier and .
