“…As a first step toward achieving HT detection through on-chip power monitoring with a focus on temperature-based analysis, a completely differential temperature sensor was introduced in this paper [29]. A temperature sensor designed with full differential configuration that uses chopper stabilized amplification was developed by modifying the input currents in the differential configuration of BJT being utilized as temperature sensors, the suggested twostage trans-impedance there has been a modification to the amplifier architecture built utilizing a chopping technique to mitigate flicker noise, the signal-to-noise ratio has greatly improved, according to simulation data [30].…”

To meet the demanding requirements of VLSI design, including improved speed, reduced power consumption, and compact architectures, various IP cores from trusted and untrusted platforms are often integrated into a single System-on-Chip (SoC). However, this convergence poses a significant security challenge, as adversaries can exploit it to extract unauthorized information, compromise system performance, and obtain secret keys. Meanwhile, traditional CMOS features have limitations in addressing hardware vulnerabilities and security threats, so promising post-silicon technologies offer potential solutions. Beyond-CMOS technologies offer avenues to fortify hardware security through distinct physical properties and nontraditional computing paradigms. These advancements bolster authentication processes, enhance key generation mechanisms, ensure hardware integrity and fortify resilience against side-channel attacks, hardware Trojans and quantum-resistant cryptography in securing hardware systems. This article provides a detailed review of hardware security, encompassing the identification and mitigation of threats, the implementation of robust countermeasures, the utilization of innovative primitives, countermeasures, various methodologies and distinct features offered by emerging technologies to resist hardware threats.Moreover, strategies to address challenges, explore future directions, and outline plans for achieving further research outcomes have been put forth in this field.

This paper introduces an on-chip analog calibration method tailored for differential temperature sensors in thermal monitoring applications. A three-step calibration process is proposed within a two-stage high-gain instrumentation amplifier to compensate for the output voltage offset due to device mismatches and on-chip temperature gradients. The calibration circuits were designed in a standard 65 nm CMOS process for simulation. Results indicate that an input-referred offset with a mean of 0.2 μV can be achieved after calibration, through which the standard deviation is greatly reduced from σ = 880.3 to σ = 5086 μV. Furthermore, the proposed analog offset calibration scheme has negligible impact on the sensitivity of the complete temperature sensor circuit, as shown by Monte Carlo and process-temperature corner simulation results.
