Simple Seamless Multi-Range Current Measurement for Applications with a Large Dynamic Range
A dual-band simultaneous sampling measuring chain was designed to suppress the noise level and to measure the energies taken and charged from and into the accumulator. The bypass switch of the sensitive range was replaced by two anti-parallel diodes. The analysis of the measuring chain noise justifies the solution used. The reached signal-to-noise ratio is up to 156 dB compared to the original one of 86 dB for 24 bit ADC.
