Ultra low energy and area efficient charge pump with automatic clock controller in 65 nm CMOS

Mohammadi, Babak LU and Rodrigues, Joachim LU (2016) 11th IEEE Asian Solid-State Circuits Conference, A-SSCC 2015
Abstract

A low power CMOS charge pump (CP) is proposed utilizing a new combination of charge transferring switches for a faster start-up, higher efficiency and lower reverse charge sharing. A low cost feedback mechanism observes the output voltage level and automatically switches off the clock after passing a threshold, which reduces energy dissipation by 62%. It is shown that by using one capacitor per stage, the proposed architecture reaches higher voltages compared to the competitive architectures when driving capacitive loads. The design is manufactured in a 65 nm technology, and measurement results confirm a 120% higher voltage compared to the conventional Dickson CP at 400 mV with identical area cost. The measured minimum operating voltage... (More)

A low power CMOS charge pump (CP) is proposed utilizing a new combination of charge transferring switches for a faster start-up, higher efficiency and lower reverse charge sharing. A low cost feedback mechanism observes the output voltage level and automatically switches off the clock after passing a threshold, which reduces energy dissipation by 62%. It is shown that by using one capacitor per stage, the proposed architecture reaches higher voltages compared to the competitive architectures when driving capacitive loads. The design is manufactured in a 65 nm technology, and measurement results confirm a 120% higher voltage compared to the conventional Dickson CP at 400 mV with identical area cost. The measured minimum operating voltage and highest charge pumping efficiency are 290 mV and 86%, respectively.
