Determine output voltage of analog multiplier provided with two input signal Vx and Vy.
A. Vo = (Vx ×Vx) / Vy
B. Vo = (Vx ×Vy / Vref
C. Vo = (Vy ×Vy) / Vx
D. Vo = (Vx ×Vy) / Vref2
Answer:A
Determine output voltage of analog multiplier provided with two input signal Vx and Vy.
A. Vo = (Vx ×Vx) / Vy B. Vo = (Vx ×Vy / Vref C. Vo = (Vy ×Vy) / Vx D. Vo = (Vx ×Vy) / Vref2
Explanation: The output is the product of two inputs divided by a reference voltage in analog multiplier. Thus, the output voltage is a scaled version of x and y inputs.
