Abstract
FinFET devices with superior ability in controlling leakage and minimizing short channel effects are anticipated to replace CMOS devices in the near future. This paper presents a design of voltage sensor in 32 nm FinFET. Based on the operation of a p-type FinFET in low-power mode and independent-gate mode, a new technique for designing a controllable delay element (CDE) with high linearity is presented. Then, we develop a 9-bit digital voltage sensor with a voltage range of 0.7 - 1.1 V and 50 mV resolution. The proposed voltage sensor can operate with ultra-low power, a wide voltage range, and fairly high frequency (i.e., 100 MHz).
