Abstract. This paper proposes admittance matrix models to approach the behavior of six modern multiport functional blocks called: differential difference amplifier, differential difference operational floating amplifier, differential difference operational mirror amplifier, differential difference current conveyor, current backward transconductance amplifier and current differencing transconduc...

Amplifying devices where the gain is automatically controlled by the level of the input signal performs dynamics processing. Non-linear components simulating tube amplifiers can be used in these devices to make musical signal audibly dense [1]. This paper deals with the simulation of tube amplifiers using the power polynomial approximation of transfer characteristic and their use in dynamic ran...

The base-band analog processor performs necessary signal processing on the 150 MHz base-band signal in the transmit and receive signal paths for a wide-band wireless local area network. The individual channel characteristics depend on the RF signal fade and interference. Broadcasting to multiple appliances requires channel equalization at the receiver. In the receive (Rx) section, the wide-band...

Semiconductor laser amplifiers have been subject of great interest for several years now. Travelling wave semiconductor laser amplifiers have recently been implemented in optical fibre communication systems as optical repeaters and optical preamplifiers. Automatic gain control (AGC) of laser amplifiers is required in more reliable optical communication systems to compensate for the effect relat...

Sense amplifiers plays an important role in memories like Dynamic Random Access (DRAM) and Static Random Access (SRAM) for read and write operations. A sense amplifier compares the bit line voltage and its complement amplifies it to rail to rail output voltages. In this project, we mainly concentrated on the write operation. Sense amplifier is one of the peripheral circuits in memories that are...

Monolithic integration of Al2O3:Er3+ amplifier technology with passive silicon-on-insulator waveguides is demonstrated. A signal enhancement of >7 dB at 1533 nm wavelength is obtained. The straightforward wafer-scale fabrication process, which includes reactive co-sputtering and subsequent reactive ion etching, allows for parallel integration of multiple amplifier and laser sections with silico...

This paper describes a 1GHz differential to single-ended amplifier for instrumentation. The unity gain amplifier can directly drive a 50Ω load with a common-mode voltage centered at ground and can accept up to a 1 VP-P input signal. The measured noise floor is below 20nV/√Hz for most of the bandwidth and the common-mode rejection is 20dB at 1GHz.

A statistically based modeling technique is developed for characterizing in-band and out-of-band intermodulation and cross-modulation distortions in multichannel amplifier environments. The model is based on a new multiple envelope memoryless behavioral model that captures the black-box characteristics of multichannel amplifiers. A power amplifier with a two code-division multiple-access channe...

This paper demonstrated the first 2-stage, 2.8W, 1.8V, 1.9GHz fully-integrated DAT power amplifier with 500 input and output matching using 0.18pm CMOS transistors. It has a small-signal gain of 27dB. The amplifier provides 2.8W of power into a 50n load with a PAE of 50%.

This paper presents the small-signal operation of a $g_{\mathrm {m}}$ -boosted inverter-cascode transimpedance amplifier which has not been reported previously and whose comprehensive analysis is available in any article or text-book. A simplified sequential equivalent-circuit method employed eliminates need for complicated circuit techniques. The shows that gain gain-bandwidth transimpedance-a...
