Emitter Static Bias Circuit of Common Emitter Amplifier The emitter static potential and bias voltage forming circuit (i.e., voltage follower) of the common-emitter amplifiers V502, V504, and V506 is shown in FIG3. The active filter composed of V507, VD502, VD503, R534, R535, C514, and R540 is the emitter

         The three-op-amp instrumentation amplifier shown in Figure 1 appears to be a simple structure because it uses the basic operational amplifier (op amp) that has been around for decades to obtain a differential input signal. The input offset voltage error of an op amp is well understood. The definition of op am

The MAX4372 low-cost, high-precision, high-side current-sense amplifier is available in a tiny, space-saving SOT23-5-pin package. Available in three gain versions (T = 20V/V, F = 50V/V, and H = 100V/V), the device operates from a single 2.7V to 28V supply and consumes only 30μA. It features a voltage output that elimi

Designers of multimedia products must provide high-quality audio effects, including high-output speaker modes. These places greater demands on system audio amplifiers. Linear amplifiers are 50% efficient, so a small increase in output power results in a significant increase in current consumption and excessive heat di

An amplifier is a device that can amplify the voltage or power of an input signal. It is composed of electron tubes or transistors, power transformers and other electrical components. It is used in various devices such as communications, broadcasting, radar, television, and automatic control. Principle: The high-frequ

Nowadays, the output of the automobile power supply system is complex. The operation of high-current motors, solenoid valves and other components, as well as the different working modes of the car and changes in the climate environment may cause fluctuations in the power supply voltage. This voltage fluctuat

It's not always obvious how an op amp's gain-bandwidth product (GBW) will affect your circuit. Macromodels have a fixed GBW. While you can look deeper into these models, it's certainly best not to mess around with them. So what can you do? You can use the generic amplifier model in SPICE to test your circuit's sens
