Sensors, Vol. 19, Pages 4343: An Amplifier-Less Acquisition Chain for Power Measurements in Series Resonant Inverters Sensors doi: 10.3390/s19194343 Authors: Jorge Villa José I. Artigas Luis A. Barragán Denis Navarro Successive approximation register (SAR) analog-to-digital converter (ADC) manufacturers recommend the use of a driver amplifier to achieve the best performance. When a driver amplifier is not used, the conversion speed is severely penalized because of the need to meet the settling time constraint. This paper proposes a simple digital correction method to raise the performance (conversion speed and/or accuracy) when the acquisition chain lacks a driver amplifier. It is intended to reduce the cost, size and power consumption of the conditioning circuit while maintaining acceptable performance. The method is applied to the measurement of the output power delivered by a series resonant inverter for domestic induction heating.
