A fluid level sensor, used to measure water level in a reservoir, outputs a voltage directly proportional to fluid level. Unfortunately, the sensitivity of the sensor drifts about 10% over time. Some means for tuning the sensitivity is required. Your engineering team produces the simple OTA circuit in figure.

(a) Show that either VG or RG can be used to vary the sensitivity.

(b) List all pros and cons you can think of for these two options.?
