【 摘 要 】

An experimental investigation of metrological characteristics of designed Universal Sensors and Transducers Interface (USTI-MOB) integrated circuit is described in the article. The USTI- MOB is based on the four novel patented methods for frequency (period), its ratio, phase shift and duty- cycle measurements, and has a non-redundant conversion time. Experiments have confirmed the high metrological performance at low power consumption (0.35 mA current consumption at Vcc = 1.8 V). So, the relative error of frequency and period measurements is constant in the whole specified measuring range of frequencies (from 0.25 Hz to 1.95 MHz) and with 95 % confidence does not exceed ±0.00089 % in the worst case. Metrological characteristics of measurements of other frequency-time parameters of signals make the USTI-MOB very suitable for various sensor systems design for mobile devices, IoT, etc.
