Pan, S. (author), Gürleyük, C. (author), Pimenta, Matheus F. (author), Makinwa, K.A.A. (author)Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm <sup>2</sup> ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm <sup>2</sup> resistor-based sensor that uses a...conference paper 2019

Gürleyük, C. (author), Pedala', L. (author), Sebastiano, F. (author), Makinwa, K.A.A. (author)To comply with wired communication standards such as USB, SATA and PCI/PCI-E, systems-on-chip require frequency references with better than 300ppm accuracy. LC-based references achieve 100ppm accuracy [1], but suffer from high power consumption (∼20mW). Thermal diffusivity (TD) references require less power (∼2mW), at the expense of less...conference paper 2018

Pan, S. (author), Jiang, H. (author), Makinwa, K.A.A. (author)This paper presents the most energy-efficient CMOS temperature sensor ever reported, with a resolution FoM of 49fJ·K2, 2.7× better than the state-of-the-art. It consists of a Wheatstone bridge made from poly-silicon resistors, which is readout by a 2nd-order Continuous-Time Delta-Sigma modulator (CTDSM). This approach leads to a high resolution ...conference paper 2017
