The circuit was designed for the purpose of creating a voltmeter with high impedance that would measure Direct Current voltages across any types of circuits. CA3130 – a BiMOS operational amplifier ...

Chopper amplifiers are generally considered as a perfect choice in applications where DC precision is mandatory. This kind of amplifier uses a continuous time modulation technique to exhibit extremely ...

Frequency mixers are often implemented using a diode bridge or a Gilbert cell. Both types of mixers use a local oscillator (LO) to flip the polarity of the radio-frequency (RF) input. When the LO is ...

Modern op amps have much higher operating bandwidths than their predecessors. These new devices are excellent building blocks that can greatly simplify the design and construction of high-bandwidth ...
