As a step toward automatic circuit understanding, we present a new method for analyzing circuit structures. We view circuits as sentences, and their elements as words. The electrical behavior and functions are the meaning of the sentences. Circuit structures are defined by a logic grammar called DCSG. A set of grammar rules, when converted into Prolog clauses, forms a logic program which perfor...

Nanometer CMOS VLSI circuits are highly sensitive to soft errors, also known as single-event upsets (SEU) that induce current pulses at random times and at random locations in a digital circuit. Environmental causes of SEU include cosmic radiation and high-energy particles. Our neutron induced soft error rate (SER) estimation method propagates single event transient (SET) pulses through the aff...

The superconductor-ferromagnet thermoelectric detector (SFTED) is a novel ultrasensitive radiation based on the giant effect in superconductorferromagnet tunnel junctions. We demonstrate analytical models and solutions time domain for SFTED operated as microcalorimeter (pulse excitation), linear smallsignal limit. Based these solutions, signal current temperature pulse response were studied two...

A high voltage and nanosecond Blumlein pulse generator has been developed to produce an output pulse whose voltage level is greater than 250 kV and pulse duration 5 ns. The generator consists of various components such as a charging circuit, a pulse transformer, and a spark gap switch. As a heart of the generator, a Blumlein pulse forming line has been constructed in the cylindrical form using ...

MEMS microrobot is less than 5 mm width, length, and height in size. MEMS microrobot is made from a silicon wafer fabricated by micro fabrication technology to realize the small size mechanical components. The mechanic...

In this paper we present an electronic circuit for position or capacitance estimation of MEMS electrostatic actuators based on a switched capacitor technique. The circuit uses a capacitive divider configuration composed by a fixed capacitor and the variable capacitance of the electrostatic actuator for generating a signal that is a function of the input voltage and capacitive ratio. The propose...

This thesis describes the development of integrated structures and circuit implementations for the receiver channel of portable pulsed time-of-flight laser rangefinders for industrial measurement applications where the measurement range is from ~ 1 m to ~ 100 m to noncooperative targets and the required measurement accuracy is from a few millimetres to a few centimetres. The receiver channel is...

As mentioned in the October 1950 report, three-path reception is troubled by impulsive noise. Each noise impulse is accompanied by an ultrasonic burst. This suggests that the ultrasonic signal be rectified and used to operate gate circuits for repairing the audio output of the receiver. A block diagram of the receiving system emphasizing the repair circuits is shown in Fig. VIII-1. The receiver...

A versatile 32-channel ASIC has been developed for accurate processing of high-rate pulse signals from highly segmented detectors. In contrast to conventional approaches, this circuit affords a dramatic reduction in data volume through the use of analog techniques (precision peak detectors and time-to-amplitude converters) together with fast arbitration and sequencing logic to concentrate the d...

Keithley’s Series 2300 Battery/Charger Simulators (fast transient response power supplies) are specifically designed for powering RFIC power amplifiers, mobile phone handsets, and other portable, battery-operated products in R&D and manufacturing environments. These battery-simulating power supplies are designed to recover very quickly from short-duration pulse load current changes as large as ...
