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...

Printed Circuit Board (PCB) of 50mm (L) x 10mm (W) x 0.8mm (H). The Printed Circuit Assembly is composed of a set of case A ATC capacitors (American Technical Ceramic, New York) allowing a 63.7 MHz tuning and a 50 Ω matching. An active decoupling circuit was also included using a PIN diode (Temex DH 80106 PIN diode) driven by the MR system during RF pulse transmission. As for the optical modali...

KANJ, HOUSSAM. Circuit-Level Modeling of Laser Diodes. (Under the direction of Dr. Michael B. Steer.) In all semiconductor laser diodes the thermal, electrical, and optical characteristics are integrally related. In this work, a new approach to the modeling of laser diodes that integrates electrical, optical and thermal effects is presented. Also, it is demonstrated how physical device models b...

Dynamic logic style is used in high performance circuit designs because of its faster speed and lesser transistor requirement as compared to static CMOS logic style. Dynamic logic has inherent disadvantages like less noise immunity and high power consumption. In this paper we have proposed a novel circuit technique for implementing dynamic gate. The proposed circuit has very less power dissipat...

In adiabatic switching [1], the registers as part of the circuitry, up to now have not been examined very well. Known approaches will be either only partially adiabatic [2], or integral part of the combinatorial logic, making automatic design hard [8, 5]. They are, however, a crucial part of the design. First, because in the registers information is stored, so here all the problems connected wi...

For three fundamental input-protection schemes suitable for high-frequency CMOS ICs, which utilize protection devices such as NMOS transistors, thyristors, and diodes, we attempt an in-depth comparison on HBM ESD robustness in terms of lattice heating inside protection devices and peak voltages developed across gate oxides in input buffers, based on DC, mixed-mode transient, and AC analyses uti...
