The PVT Sensor IP consists of SAR ADC, bandgap circuit, oscillator, and digital logic. The SAR ADC is a successive approximation analog-to-digital converter. The bandgap circuit generates an accurate reference voltage for the SAR ADC and automatically adjust the supply voltage based on temperature coefficients. This temperature-related voltage or external input voltage is sampled by the SAR ADC and converted to a digital signal. The oscillator generates a clock for process corner detection. The digital logic receives clock and control signals from SoC, and then it outputs measurement results to SoC.
