This paper presents a 20 Gb/s injection-locked clock and data recovery (CDR) circuit for burst mode applications. Utilizing a half rate injection-locked oscillator (ILO) in the proposed CDR circuit leads to higher speed operation and lower power consumption. In addition, to accommodate process, voltage, and temperature (PVT) variations and to increase the lock range, a frequency locked loop is ...

The paper presents project of reprogrammable chip – FPGA, designed with current-mode gates novel digital gates operating with constant, continuous power supply current. Such continuous supply is a perfect one for analog-digital circuits, which are located on the same single die. Switching of digital part of the chip don’t disturb analog part. Based on the proposed approaches to minimizing logic...

Fluid compressibility has a major influence on the efficiency of switch-mode hydraulic circuits due to the release of energy stored in fluid compression during each switching cycle and the increased flow rate through the high-speed valve during transition events. Multiple models existing in the literature for fluid bulk modulus, the inverse of the compressibility, are reviewed and compared with...

This paper discusses the design and simulation of Slope compensated Current mode Controlled Boost converter which is used in several applications like regulated switch mode dc-dc power supplies. There are several types of dc-dc converters. A boost converter simply steps up a source voltage to a higher, regulated voltage. This allows one power supply to provide different voltage levels at differ...

In this paper, a novel approach has been suggested to obtain an improved spurious-free window for dielectric resonator in microwave integrated circuit environment. In microwave integrated circuit environment, the dielectric resonator placed on a thin dielectric substrate gets located asymmetrically with respect to its shielding enclosure. A reduced separation in frequencies (mode separation) is...

1. Introduction Among the different design for testability (DFT) techniques available today, scan path based methods [Williams 83] are probably the most basic and most widely used. In a scan-path based design, the circuit has two operating modes; the normal functional mode and test mode during which the circuit bistables are interconnected into a shift register. Thus, in the test mode, it is po...

Abstract—This article presents a current-mode universal biquadratic filter. The proposed circuit can apparently provide standard functions of the biquad filter: low-pass, high-pass, bandpass, band-reject and all-pass functions. The circuit uses 4 current controlled transconductance amplifiers (CCTAs) and 2 grounded capacitors. In addition, the pole frequency and quality factor can be adjusted b...

This article presents a current-mode quadrature oscillator. The proposed oscillator can provide 2 sinusoidal output currents with 90 0 phase difference. It also provides high output impedances that make the circuit able to directly drive load without additional current buffer. The condition of oscillation and frequency of oscillation can be controlled independently and electronically by adjusti...

The monolithic integration of enhancementand depletion-mode (Eand D-mode) high electron mobility transistors (HEMTs) lattice-matched to InP is of interest in the area of circuits for low power, high speed communications. When compared to circuits implemented in depletion-mode @-mode) only technology, circuits implemented in ED-mode technology enjoy a number of advantages. D-mode only circuits r...
