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 .
There is a LT spice folder uploaded. One can use those circuits to understand the
design steps. The design of single stage is already available in book.

2. Using the fully differential amplifier designed above , design a MOSFET-c
second order low pass filter with a pole frequency of 2MHz and a dsc gain of 4.
Use an integrating capacitor of 5pF. and Vc= 3V
