A novel interface circuit topology with power management is presented for ultra-low voltage DC-DC step-up conversion. The proposed 90 nm CMOS circuit avoids off-chip components or non-standards processes, and is suitable for ultra-low voltage system-on-chip applications. Comparative analysis was performed with a commercial low voltage DC-DC converter to identify the relative advantages and disadvantages of the integrated approach. The circuit can be started up from input voltage as low as 0.2V based on the simulations, and generates 2.3V with 12% of maximum efficiency.

Low input voltage and high step-up integrated regulator for thermoelectric energy harvesting Pathirana, W. P. M. R.; Jayaweera, H. M. P. C.; Muhtaroglu, Ali (2015-03-26) This paper presents a low input voltage and high step-up fully integrated DC-DC regulator in 0.18 mu m standard CMOS technology for thermoelectric micro-power generation. The circuit avoids off-chip components, non-standard processes, and is thus suitable for ultra-low voltage low profile system-on-chip applications. The proposed system can deliver a regulated output voltage of 1.5 V at 31 mu W output power with an input voltage as low as 0.2 V. The maximum simulated efficiency is 22% at the given step-up r...
Low voltage integrated charge pump circuits for energy harvesting applications Pathirana, Walive Pathiranage Manula Randhika; Muhtaroğlu, Ali; Sustainable Environment and Energy Systems (2014-7) Two different low voltage integrated charge pump circuit topologies are studied in this thesis for energy harvesting applications. The circuits are implemented in 0.18 μm standard CMOS technology without the use of off-chip magnetic components and non-standard processes, and are thus suitable for low profile (small and low cost) system-on-chip applications. In the first proposed design, operation at low input voltage (~240 mV) is achieved with a 5-stage subthreshold first stage oscillator, which improves th...
Stage Optimization in Regulated Step-Up for Low Voltage Electromagnetic Energy Harvesters Ulusan, Hasan; Zorlu, Ozge; Külah, Haluk; Muhtaroglu, Ali (2015-03-26) This paper presents a performance enhancement feature for a novel power management circuit to generate 1.8 V from the low DC voltage rectified at the output of the vibration-based electromagnetic (EM) energy harvesters. The proposed 180 nm circuit utilizes a low voltage charge pump based boost converter with variable output-stages, and an autonomous regulator circuit with negative feedback topology. 2 and 3 stage charge pump options in the variable stage configuration has been validated to extend the suppor...
Design optimization of a fully integrated charge-pump with LC tank oscillator for ultra-low voltage energy harvesting Jayaweera, H. M. P. C.; Muhtaroglu, Ali (2017-01-01) Model based optimization of a novel integrated interface circuit topology is presented for low voltage DC-DC step-up conversion. A cross-coupled charge pump is implemented in standard 0.18 mu m CMOS technology using an integrated LC tank oscillator to enable a compact, low cost, self-starting solution with maximum efficiency at ultra-low input voltage levels available from embedded micro-power generators. The voltage doubling oscillator can start up with input as low as 0.10 V. Full system can step 0.2 V up...
