Process/Voltage/ Temperature Sensor

Innosilicon PVT Sensor IP is designed for on-chip temperature measurement. Besides temperature, it also can measure on-chip voltage, such as core power supply voltage, which can be used to monitor the IR drop on core power supply.
Innosilicon PVT Sensor IP consists of SARADC, bandgap circuit, voltage buffers, mux circuit, oscillator and digital logic. The SARADC is 10-bit successive approximation analog-to-digital converter. The sampling rate is up to 100KS/s. The bandgap circuit produces an accurate voltage with very small temperature coefficient, which is used as the reference voltage of SARADC. The bandgap circuit also produces a voltage that is related to temperature. This voltage is sampled by SARADC and converted to digital signal. The oscillator generates a clock to detect process corner. The digital logic receives clock and control signals from SoC logic, and outputs measurement result data to SoC logic.
Innosilicon PVT Sensor IP offers reliable implementation for on-chip temperature or voltage measurement applications.
