Abstract: This paper focuses on the non-inverting buck-boost converter supplying an adjustable DC voltage to a WCDMA RF power amplifier (RFPA) in order to improve the system efficiency under different ...

Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken ...

This MCC based MPLAB X example shows how to calibrate the gain and offset of the OPAMP when configured as a Programmable Gain Amplifier (PGA). The internal DAC and ADC are used to perform the ...

In the world of audiophilia there are arguments that rage over the relative merits of particular components. Sometimes this can reach silly levels as in the high-end ALPS pot we once saw chosen as a ...

Abstract: This paper presents a supply-variation-tolerant transimpedance amplifier (TIA). For parallel integration of optical transceivers, supply voltage variation is one of the serious problems. We ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...
