The payment device includes a NFC antenna, a boost converter (voltage regulator) chip. A first feedback circuit is connected to the NFC antenna and the feedback pin of the boost converter chip. The boost converter chip regulates a first voltage provided to the NFC antenna for the NFC antenna to modulate a field. A second feedback circuit includes a microcontroller with an ADC input and a DAC output. ADC input is connected to NFC antenna, and DAC is connected to the feedback pin of the boost converter chip. The microcontroller receives the voltage at the ADC input and controls the DAC output to transition based on the value of the ADC input."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Feedback control loop for NFC transmitter voltage control","description":"A payment object reader configured to read data from NFC or EMV enabled payment objects.
