Abstract(in English) | A ΔΣ modulator using a frequency modulation intermediate signal was demonstrated using a resonant tunneling logic gate MOBILE. This ΔΣ modulator is based on the nature of an FM signal and suitable for high speed operation. Experiments using an InP-based MOBILE demonstrate good noise shaping characteristics. Moreover, the operation with a higher FM carrier frequency than the sampling frequency was demonstrated, which shows a good noise shaping as well as the previous one. This makes the design of the voltage controlled oscillator, which is a key component of the FM ΔΣ modulator, much easier. We have also discussed how to increase the order of the FM ΔΣ modulator using MOBILEs. Consequently, an FM ΔΣ modulator using MOBILE is promising for high resolution, wide band A/D converters. |
