A field-effect triode amplifier with series negative current feedback allows a voltage gain of the order of 200–300 to be obtained for a load resistance R s ≥1 MΩ. The coefficient K u begins to decrease noticeably only for a feedback resistance above 500 Ω.The current gain reaches (...
The effect of this is that the input impedance of a JFET amplifier will be lower, perhaps by several orders of magnitude, than that calculated from the IGSS figure once the IG breakpoint is exceeded. This places a limit on the effective common-mode input voltage range. Note that p-channel...
Feedback is a method in which a portion of the output returned to the input in order to modify the characteristics of the device. Feedback can applied to transistor amplifier circuits to modify their performance characteristics such as gain, bandwidth, input and output impedance etc.. There are...

An InP-based HBT technology with peak f/sub t/ /spl sim/ 135GHz is used to design and fabricate several 3-stage limiting amplifier with high margin at >40Gbps. Feedback techniques are used in all design for the first two stages. The different designs compare the conventional (resistive lo...
In this work, we report modeling of non-Markovian open quantum systems, consisting of an excitonic dimer that displays memory effect due to time delayed interaction with its environment. We, indeed investigate the effect of these time delays on quantum coherence and excitation dynamical behavior in...

By applying a voltage to the gate contact, an electric field is established through the oxide and the transistor can be turned on or off. MOSFETs can be used as switch or amplifier in the circuits. In case of a switch, the resistance RDS is dependent on VGS (RDS=f(VGS)). The ...

Also, the amplitude of noise is varied to quantize the amount of phase noise degradation with respect to noise amplitude on supply. To obtain a noisy dc supply, noise from a function generator is added to the linear dc supply using a negative feedback operational-amplifier circuit shown in ...
