High-impedance circuits, by nature, involve the use of high value resistors. Values range from hundreds of kilo-ohms up into the hundreds of Megohms and even as high as tens of Teraohms. Beyond the ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Electrical engineers designing analog electronics commonly have to drive a capacitive load with an operational amplifier that cannot quite handle the required capacitance. Common approaches to ...

Current-mode (CM) active elements provide the advantages of high slew rate and wide bandwidth. One important CM building block is the second-generation current-controlled conveyor (CCCII) (Fig. 1).

Capacitive sensor interfaces are critical to the accurate measurement of physical parameters such as pressure, humidity, and force across a broad range of applications including biomedical devices, ...
