摘要

An all-digital cantilever controller for magnetic resonance force microscopy (MRFM) was developed through a close collaboration between SC Solutions (Sunnyvale, CA), Cornell University (Ithaca, NY), and the U S Army Research Laboratory (Adelphi, MD), The advantage of an all-digital controller is its absence of thermal drift as well as its great tuning flexibility The versatile controller comprises a field-programmable gate array (FPGA) connected via a low-latency interface to an analog input, an analog output, and a digital signal processor (DSP) with additional analog outputs. Performance of the controller was demonstrated in experiments employing ultrasensitive silicon microcantilevers fabricated at Cornell University's Nanoscale Science and Technology Facility.
