Abstract :
A new current comparator is proposed that is optimised for low power consumption whilst maintaining high speed. This novel comparator design offers a reduction in power consumption of over three orders of magnitude compared with other high-speed designs, and allows picoampere current decisions at kilohertz frequencies. Circuit simulations were performed in Cadence software for a standard 0.35 mum process.
