7.) In the in the cascaded summing / inverting / noninverting operational amplifier circuit shown in...
Design a circuit using 2 cascaded operational amplifier circuits to perform the mathematical average of 3 inputs: V1, V2, V3. HINT: use an inverting summing amplifier followed by an inverting amplifier (cascading means the output of the 1st amplifier is connected to the input of the second amplifier).
Given below is a differential operational amplifier in block form and its internal transistor circuit with VCC=20V, VEE= 12 V , RC=5kΩ,RE=1kΩ and R1=2kΩ. Assume that the transistors are identical and have a βac=βdc=100. An ac signal Vi(t)=5sin(10t) is applied to the input terminals where Terminal 1 is Positive (non-invertinq) & Terminal 2 is negative (inverting) as stated in the cases below. Draw the output signals in each case. : a) V1=Vi(t) , V2=Grounded. Vo(t)=Vo2-Vo1 ) b) V1=Grounded , V2=Vi(t)....
