“Green” pathways for test, measurement and instrumentation
Today, the instrument is expected to be carried to the field, running on battery power and achieving even greater accuracy instantly. Analogue circuitry does not benefit from the scaling effects of smaller geometries in the same manner as digital circuitry. Noise, the enemy of precision measurements, actually increases if less power is consumed. And the signal-to-noise ratio (SNR) understandably gets worse with new low voltage processes as the signal amplitude is decreased.
Then how does the analog signal chain “go green” while increasing performance?
