Answers question in I/Q Noise figure, and on how to do stability in Cadence ADE.

IM2 Consider the fully differential amplifier shown below:

The two inverters chasing their tail to the right of the input inverters represent a memory unit (i.e. a latch). When one output is high the other one is forced low. This low output then reinforces the first output being high. These two inverters form a positive feedback system.

I wanted to go through a bit of illustration with regard to minimizing MOS diffusion parasitics. I will start with the basics of detailing the MOS semiconductor structure. From there, I’ll display some layout configurations that minimize MOS diffusion capacitance.

I was asked a question on how to reduce leakage for digital circuits. I started by detailing process options that effect leakage, each effective both leakage and circuit performance. In this article, I will detail two methods to reduce leakage while maintaining circuit performance. I assume that the circuit at hand requires the highest performance […]
