Carissa Sipp, Systems Engineer, brings us this session. Fully differential amplifiers (FDAs) are versatile tools to use in a signal chain, and they offer a variety of benefits. Fully differential ...

The traditional three op-amp differential amplifier's signal to noise ratio can be improved by 6dB by adding a resistor and slightly changing the connections. There is a trade-off though: The ...

This basic differential amplifier, while appearing not very complicated, is unconventional in that it operates the EPAD MOSFET devices in the subthreshold region. Therefore it requires a different ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...

Differential amplifier circuits, such as the one illustrated in Figure 1, are required in analogue technology for a wide variety of applications. One example is measurement technology in which, ...

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 ...

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp INA ...

The most common device for the measurement of load, pressure, torque, and even piezo-resistive (low frequency) acceleration is the strain gauge transducer. As a transducer, which converts a measured ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
