Differential Voltage Generator (DVG)
A source that produces two output voltages equal in magnitude but opposite in polarity with respect to a common reference (e.g., +V and –V).
To provide a differential input for circuits like ADCs, amplifiers, and measurement systems, improving noise immunity.
Why is a DVG useful?
Single-ended input
Measures signal relative to ground, more prone to noise interference.
Differential input
Measures (V_+) - (V_-)
Rejects common noise
Has higher accuracy
