What is the bandwidth of the current measurement circuit? What is the DC gain of the circuit? How can we alter this circuit and double the bandwidth with out changing the gain? The 0.4pF capacitance ...
Figure 1 is based on the OP37 which has an impressive list of specs. They include a 60 MHz gain-bandwidth, making 20 kHz bandwidth compatible with gain up to 3000x = +70 dB, noise ~3 nV/Hz 1/2 which ...
The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...
Voltage-Feedback operational amplifiers (VFA op amps) allow circuit designers to swap gain for bandwidth. current-feedback op amps (CFAs) are simpler to use than VFAs, but do not offer gain-bandwidth ...
The OPA657 is a high-gain-bandwidth (1.6-GHz) JFET amplifier designed for optical networking, photodiode, and data-acquisition applications. It combines a high-precision voltage feedback amplifier ...
