It is well known to analog experts that you can use the positive and negative inputs of an operationalamplifier to make a high-impedance current source (current pump) using a conventional operationalamplifier (op amp). This basic circuit can put out both + and - output current (or zero current) into variousloads. The theory is simple. But the practical problems involved are not so simple or

In an LCD the backlight shines through the liquid crystal material and the voltage across the liquid crystal controls how much light shines through it. An active matrix LCD (AMLCD) contains many pixels arranged in a grid pattern. The voltage across each pixel is controlled individually so that high resolution images can be created. One terminal of every pixel is connected to a common plane. The v

Driving a capacitor also entails the Op Amp's output current capability since changing the voltage across acapacitor requires an adequate supply of current from the Op Amp. This application report presents a labmethod to measure amplifier stability under closed loop condition. In addition, a new Op Amp architectureis presented that would ease this class of applications by using an internal m
