This paper presents a new design of a BJT-based temperature sensor in a CMOS, with an inaccuracy of . In order to achieve high accuracy, high reliability, and self-detection capability in the sensor system, we mainly make following innovations. First, we adopt an improved chopper technique with two sub-OPAMPs instead of one OPAMP traditionally. By applying programmable delay lines and real-time calibration, we achieve precise phase control.

1.0 Prologue At the end of World War II, a young officer from the British army was granted immediate demobilization to return to Cambridge in order to complete his degree, which had been interrupted by the war. He had enlisted in the army in 1941 at the age of 20 and had led a unit of four tanks as part of the Guards Armoured Division during the battle for Normandy.
