The differential stage has two input transistors (Q1, Q2) responding to two input voltage components (V+v, V-v). The transistors are connected to a constant current source (15) and form two branches of a differential output, the collectors of each transistor being connected to the emitter ...
A high-input-impedance transistor amplifiers, requiring no high-resistance resistors, is useful in integrated circuitry. A negative feedback circuit splits a quiescent current into first and second portions in the ratio of the collector and base currents of an amplifier transistor. The first portion...
The input amplifier includes MOS-transistors (6,7) and a single-ended current disconnection for input signals having steep edges. Also provided is at least one transistor (7) having an electrode connected to the output. A further transistor, e.g. NMOS, (21) prevents complete switch-off of ...

In a typical operational amplifier circuit, a portion of the output is fed back to the inverting input. Errors that are present on the output which were generated in the loop are multiplied by the feedback factor (β) and subtracted out. This helps maintain the fidelity of the outpu...

To measure signals containing negative common-mode voltages, the common-mode input must be raised off the negative rail. To measure negative signals, the amplifier output must be raised off the negative rail. Both of these level shifts can be accomplished by applying a positive voltage to the ...

It is apparent that current-sense amplifiers and difference amplifiers perform the same function while operating quite differently. A difference amplifier attenuates high input voltages to bring the signal to a level the amplifier can tolerate. A current-sense amplifier converts the differential input ...
