I’ve been doing some statistical measurements lately (more to follow). It occurs to me that while most people measure the mean of a set of measurements, the median is more useful.

Introduction I had been working on a pulse-width-modulation (PWM) design. It was a pseudo-digital implementation, in that the output was clocked by a high-speed clock. The actual switching rate was much lower than this clock. I wanted to simulate this design in Cadence/Spectre by running a transient and then taking an FFT. However, I ran […]

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 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 […]

I received an inquiry on how to reduce leakage. I will cover how to do so in a future article. However, before I do, let’s go over some process options that effect leakage.
