In a regime of nonlinear dynamics, a shift of the oscillator resonant frequency is discovered which has a direct analogy to the switching of a dc-biased Josephson junction into voltage state. Results are reviewed for the predicted charge sensitivity, and it is shown that a performance challenging the best rf-SETs is foreseeable with the new device.4 pages, submitted to Proceedings of the Vth Rencontres de Moriond in Mesoscopic PhysicsMesoscale and Nanoscale Physicstext
