Abstract
This paper proposes a fully integrated hybrid Dickson and continuously-scalable-conversion-ratio (CSCR) converter for bipolar-input thermoelectric energy harvesting (TEH). This is the first reported fully integrated converter achieving dualpolarity operation with an extended voltage conversion ratio (VCR) range, thanks to the 4-rail CSCR topology and the reconfigurable hybrid Dickson-CSCR architecture. The TEH interface system is fabricated in a $180-\text{nm}$ BCD process, achieving above 75 % efficiency for VCR ranging from -6.48 to -2.55 and from 2.55 to 6.67 with a 1.2 V regulated output.
