Current Mode Logic Active Inductor Load

Active inductor load can be designed by applying a negative voltage feedback from drain of an active current load to the gate of the active load. The feedback has a time constant that depends on the size of gate resistor and Cgs of the active load. Overall, feedback makes the load to behave like an inductor where $L=\frac{R_g C_{gs}}{g_m}$. For more details refer to page 68 of this Master's thesis. The following image is also captured from the thesis.

Spectre Simulation (Fundamental)

"Simulation of Analog and Mixed-Signal Circuits by Ken Kundert" slides are a quick review of the book, "The Designer's Guide to SPICE and Spectre". The book goes through the details of spice simulation and explains the trad-offs.

CMOS chopper amplifier to reduce 1/f noise

The paper reviews CMOS chopper amplifier theory and actual circuit. The theory is simple: modulate the input signal to F_chopper where 1/f noise is not significant, amplify the modulated signal. and finally demodulate and reconstruct low pass signal at the output. Also, found this work interesting: using CMOS devices in lateral bipolar mode to decrease 1/f noise (see figure 14).
