A low-voltage programmable-gain current-mode amplifier
A CMOS low-voltage, wide-band continuous-time current amplifier is presented. Based on an open-loop topology, the circuit is composed by transresistance and transconductance stages built around triode-operating transistors. ...
Simple Real-Time Digital PWM Implementation for class-D Amplifiers With Distortion-free Baseband
(Institute Of Electrical And Electronics Engineers, 2014-10)
A real-time, digital algorithm for pulse width modulation (PWM) with distortion-free baseband is developed in this paper. The algorithm not only eliminates the intrinsic baseband distortion of digital PWM but also avoids ...
Design of a LNA and a Gilbert Cell Mixer MMICs with a GaAs PHEMT technology
The design of a Gilbert Cell Mixer and a low noise amplifier (LNA), using GaAs PHEMT technology is presented. The compatibility is shown for co-integration of both block on the same chip, to form a high performance 1.9 GHz ...
A low-voltage programmable-gain CMOS amplifier with very-low temperature-drift
A new topology for a LVLP variable-gain CMOS amplifier is presented. Input- and load-stage are built around triode-transconductors so that voltage-gain is fully defined by a linear relationship involving only device-geometries ...
Radial basis function network applied to the linearization of a voltage controlled oscillator
An analog circuit that implements a radial basis function network is presented. The proposed circuit allows the adjustment of all shape parameters of the radial functions, i.e., amplitude, center and width. The implemented ...
