Unformatted text preview: from the equation: R ds =1/d(i d )/d(v ds )=V p ^2/2i dss (v gsv p )^2 Q6: Applications of a voltage controlled resistor: • variable resistance • small signal amplifier • switch Q7: Output voltages corresponding to logic 1 are:40.2mV(when v in1 =5V,v in2 =0) and 37.8mV(when v in1 =0,v in2 =5V) Output voltage corresponding to logic 0(v in1 =0,v in2 =0):4.3V Output voltage corresponding v in1 =5Vand v in2 =5V is:15.52mV we can observe that when both of the two input voltages are of logic 1 the output voltage is much smaller than when input is of logic 1 and the other of logic 0. Q8: When adding the 470 ohms the low voltage is decreased, increasing the resistor would lower the value of the output voltage. Q9: At V in =2.4V the output changes states....
