A Digitally Controlled Amplifier With Ripple Cancellation
نویسندگان
چکیده
This paper describes a large-signal linear, multirate digital controller for, among other possible servomechanical applications, charging electric vehicle batteries. This controller permits the power amplifier to track and deliver a desired current trajectory for a wide range of loads while providing a unity-power-factor interface to the electric utility. A computationally inexpensive technique for implementing output ripple cancellation is also described and demonstrated on a prototype converter.

Design of the EPC-9, a computer-controlled patch-clamp amplifier. 1. Hardware.
The EPC-9 patch-clamp amplifier is a digitally controlled analog device for recording currents in membrane patches and in small cells. It has neither front-panel controls nor internal trim adjustments; instead all gain, range-changing, transient cancellation, calibration and other functions are computer controlled. Novel aspects of the circuit design of this instrument are discussed, with speci...
متن کاملDigital Control of a PWM Switching Amplifier with Global Feedback
A digitally controlled class-D amplifier using global feedback is presented. The output signal of the amplifier is sampled using a sigma-delta analogue-to-digital converter. A novel compensation strategy is used to minimize distortion resulting from ripple feedback of the output signal. An evaluation system, based on a Field Programmable Gate Array, was developed and an experimental evaluation ...

This paper presents an improved linearity variable-gain amplifier (VGA) in 0.18-µm CMOS technology. The linearity improvement is resulted from employing a new combinational technique, which utilizes third-order-intermodulation (IM3) cancellation mechanism using second-order-intermodulation (IM2) injection, and intermodulation distortion (IMD) sinking techniques. The proposed VGA gain cell co...
