One of my previous columns explains a method for calculating decreasing open-loop-gain-induced errors (Reference 1). Several readers requested a simpler error-function explanation, so this one uses op ...

The sketch below shows a single op-amp configured as a variable gain differential amplifier that uses only one variable resistance as a gain adjustment and which maintains, if not a superb value, at ...

Standard circuits such as an inverting amplifier are your bread and butter, and the formula gain ... circuit op-amps will incorporate one in some form or another. It is a differential amplifier ...

b. The gain is set by VCC as the higher the supply voltage, the higher the gain. c. By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the ...

The circuit shown is a differential amplifier that not only offers programmability but also provides a logarithmic-type gain (Fig. 1). The traditional gain-setting resistors of the amplifier ...

Called CFBplus, these op amps unshackle the gain from the bandwidth ... This is particularly useful in the differential driver or receiver stages to equalize the high-frequency attenuation ...

Texas Instruments has introduced its first differential amplifiers which are programmable for variable gain. The 2.4GHz LMH6881 single-channel and 2.4GHz LMH6882 dual-channel amplifiers have a 6dB to ...

Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC6432-15, a wideband fully differential amplifier with 15dB gain, offering linearity of up to +50.3dBm OIP3 ...
