(a) It is almost impossible to obtain a clean voltage transition from a mechanical switch because of the phenomenon of contact bounce. This is illustrated in Figure 4a, where the bouncy switch makes and breaks contact producing several output voltage transitions. Using appropriate circuits and waveforms illustrate how such a problem can be solved electronically. +5 V 1 -VOUT 5V Random "bouncing" ov. www Switch to position 2 Switch comes to rest in position 2 Figure 4a (b) Compare the approximate hybrid model to the re-model for the CE configuration and derive the mathematical relationships between the hybrid parameters and the re- model parameters. (c) Calculate the output voltage (Vdo) for the differential input voltage Vd. Given Vd = 1mV; Vc = 1mV and Vco = 40uV for a CMRR of 97.98dBm. (d) Draw a sample circuit of a differential amplifier employing BJTS.
