Digitally Programmable-gain Amplifier Uses Divergent-exponential Curve

摘要

DPGAs (digitally programmable-gain amplifiers) are handy signal-processing components whenever ADCs must acquire signals with a wide dynamic range. Without thernability to accommodate input-signal amplitude to match and efficiently use ADC span, low-level inputs may not be digitized with adequate resolution, and high-level inputs may overrange the ADC and be lost altogether.
