If you're seeking a way to measure current and power in a circuit, you need to know about current-sense amplifiers (CSAs). A CSA is a specialized op amp connected as differential amplifier with ...

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 ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...
