Biography

Jaekyum Lee was born in 12nd July, 1986 in Seoul, Korea. He received the B.S degree in 2011 from Korea University, Seoul, Korea and the Master degree in 2013 from KAIST, Daejeon, Korea, respectively. For his Master thesis, he worked on SAR ADC which has extremely low power consumption. From 2013, he had worked for Samsung Electronics, Hwasung, Korea. During working for company, he designed CMOS image sensor for mobile phone and automotive. Since September 2018, Jaekyum has been a Ph.D candidate in the Electronic Instrumentation Laboratory at TU Delft, where he continues working on CMOS image sensor.

  1. A 5800 μm2 Resistor-based Temperature Sensor with a one-point Trimmed 3σ Inaccuracy of ±1.1 °C from −50 to 105 °C in 65 nm CMOS

    Abstract: ... This letter describes a compact resistor-based temperature sensor intended for the thermal monitoring of microprocessors and DRAMs. It consists of an RC poly phase filter (PPF) that is read out by a frequency-locked loop (FLL) based on a dual zero-crossing (ZC) detection scheme. The sensor, fabricated in 65-nm CMOS, occupies 5800 μm 2 and achieves moderate accuracy [±1.2 °C (3σ)] over a wide temperature range (-50 °C to 105 °C) after a one-point trim. This is 2x better than the previous compact resistor-based sensors. Operating from 0.85 to 1.3-V supplies, it consumes 32.5-μA and achieves 2.8-mK resolution in a 1-ms conversion time, which corresponds to a resolution FoM of 0.26 pJ·K 2.

    Abstract: ... This paper presents a compact resistor-based CMOS temperature sensor intended for dense thermal monitoring. It is based on an RC poly-phase filter (PPF), whose temperature-dependent phase shift is read out by a frequency-locked loop (FLL). The PPF's phase shift is determined by a zero-crossing (ZC) detector, allowing the rest of the FLL to be realized in an area-efficient manner. Implemented in a 65-nm CMOS technology, the sensor occupies only 7000 μm². It can operate from supply voltages as low as 0.85 V and consumes 68 μW. A sensor based on a PPF made from silicided p-poly resistors and metal-insulator-metal (MIM) capacitors achieves an inaccuracy of ±0.12 °C (3σ) from -40 °C to 85 °C and a resolution of 2.5 mK (rms) in a 1-ms conversion time. This corresponds to a resolution figure-of-merit (FoM) of 0.43 pJ·K².
