Voltaje de referencia BandGap y módulo de comunicación serial para SAR ADC 10 bits de baja potencia para aplicaciones biomédicas. Trabajo de obtención de grado, Especialidad en Diseño de Sistemas en Chip. Tlaquepaque, Jalisco: ITESO.https://hdl.handle.net/11117/7619The document presents two designs a BandGap Reference Voltage, and a Communication Serial Module for a 10 bits SAR ADC for low-power applications. Designs were implemented using TSMC 0.18 µm CMOS technology with 1.8 V supply voltage. The BandGap Reference Voltage was designed to provide a reference voltage of 900 mV ±500 µV. The bandgap was tested at simulation level under different temperature conditions to ensure constant output in a temperature range from –40 °C to 85 °C. The Communication Serial Module is designed using the hardware description language Verilog. This module receives the 10 bits parallel output of the SAR ADC and retransmits the conversion result into a serial format using the SPI format. The Communication Serial Module was tested under a simulator, where multiple test cases were applied to stimulate in different ways the module. Both circuits were designed to accomplish the SAR ADC requirements in which BandGap supplies the reference voltage to the capacitor array in the SAR ADC and the Serial Module sends the data values after the conversion is finalized.engDigital to Analog Converterinfo:eu-repo/semantics/academicSpecialization
