A transconductance amplifier with extended bandwidth, which is a critical block in various applications including amplifiers, filters and DACs is presented. The presented technique introduces a differential-mode negative capacitance while introduces the common-mode positive capacitance such that it extends the differential-mode bandwidth and compensates the common-mode stability. The proposed t...

A wideband variable gain amplifier (VGA) design is introduced with two different schemes. It is based on a fully differential amplifier with resistive loads, and a Negative Miller Capacitance technique is used to increase the bandwidth of the amplifier. The amplifier consists of three stages, and the gain is varied through the second and third stages, where they are degenerated by a voltage con...

Digital simulation of guitar tube amplifiers is still an opened topic. The efficient implementation of several parts of the guitar amplifier is presented in this paper. This implementation is based on the pre-computation of the solution of the nonlinear differential system and further approximation of the solution. It reduces the computational complexity while the accuracy is comparable with th...

Abstract This report is an outcome of a master degree project at Linköpings University in cooperation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver se...
