The feedback current amplifier in Fig. P10.26 utilizes an op amp with an input differential resistance , an open-loop gain , and an output resistance The output current that is delivered to the load resistance is sensed by the feedback network composed of the two resistances and , and a fraction is fed back to the amplifier input node. Find expressions for assuming that the feedback causes the voltage at the input node to be near ground. If the loop gain is large, what does the closed-loop current gain become? State precisely the condition under which this is obtained. For V/V, , , k , , and k , find A, , and .
Module 3 F : Sequence Generators We will design a clocked synchronous state machine and look at the minimum risk and cost. A good example of a sequencer is a digital lock. Lab Number 10! We will start with some simple character displays and look at Moore and Mealy model realizations.. A sequence generator produces a series of output signal assertions that constitute a pattern example of such include vehicle tail lights, traffic control signals, character displays, and control sequences. Two strategies include : minimum cost : unused states are assumed to be don’t cares, potentially reducing realization cost while increasing risk Minimum risk : unused states are assigned a next state, eliminating risk of undefined behavior but increasing cost. Ex : traffic light T bird sig
