Conference paper (2026) - Jida Peng, Nandor G. Toth, Kofi A.A. Makinwa
This paper describes a BJT-based temperature sensor that combines a dual-mode front-end (DMFE), and a low-power switched capacitor (SC) Δ Σ modulator with a 10-tap FIR-DAC. After a low-cost 1-point trim, it achieves ± 0.1° C(3 Σ) inaccuracy from -40° C to 85 °C while dissipating only 75 nW. This is 3 × lower than prior precision BJT-based sensors, and 2-3 × more accurate than prior low-power MOS-based sensors. ...
This work proposes a one-stage bidirectional rectifier with a pre-charge voltage (VPC) based perturb-and-observe (P&O) maximum power point tracking (MPPT) algorithm for triboelectric energy harvesting. The proposed VPC-based MPPT dynamically locates the true MPP while accounting for circuit non-idealities, using a simplified implementation compared to conventional P&O methods. Consequently, it achieves 93% MPPT efficiency and 8.86× energy enhancement compared to the full-bridge rectifier. ...
