Capacitance-to-Digital Converters Based on Universal Sensors
and Transducers Interface (USTI)
Abstract
This presentation devoted to a highly digital Universal Sensors and Transducers Interface (USTI-MOB) with low power consumption, working in the capacitance measurement mode. The developed ASIP has the input capacitance range from 50 pF to 0.1 μF and average relative error < ±0.3 %. The USTI-MOB has 1.5 mW power consumption at +1.8 V supply voltage, and use a 4 MHz quartz oscillator. The IC has three popular serial interfaces: I2C, SPI and RS232/USB. Due to high metrological performances and technical characteristics the energy-efficient USTI-MOB is well suitable for such application as sensor systems for IoT, wearable and mobile devices. The ICs can also work with any quasi-digital capacitance converters, in which the capacitance is converted to frequency, period, time interval, duty-cycle or pulse width of square wave signals.
