A digital CMOS buffer circuit with a voltage transfer characteristic (VTC) with low threshold voltage detection, hysteresis, and high noise immunity is presented. The circuit is capable of restoring slow transition times and distorted input signals with a minimum delay penalty, offering at the same time high noise immunity to glitches induced either through capacitive coupling or from the power...

We have developed a compact CMOS motiondetection circuit based on a direction-selective neuralnetwork architecture. The circuit consists of asynchronous current-mode digital subcircuits for edge detection and subthreshold analog subcircuits for motiondetection. SPICE and numerical simulations of the network show that the circuit can successfully extract edge lines from incident images and compu...

Conventionally, controllers for DC/DC converters have relied on analog circuit techniques for implementation. While analog based systems have proven successful, several reasons make digital control attractive. Digital control allows for the implementation of more functional control schemes. Digital circuits are potentially less susceptible to noise and parameter variations. With the recent expl...

The paper describes a novel method for simple estimation of jitter contained in a received digital signal. The main objective of our research was to enable a noninvasive measurement of data link properties during a regular data transmission. To evaluate the signal quality we estimate amount of jitter contained in the received signal by utilizing internal signals of a data recovery circuit. The ...
