<p>A helical resonator with a certain resonant frequency and a high-quality factor (Q-factor) is critical for an ion trap system, which results in a larger trap depth, longer trap time, and lower radiofrequency (RF) noise. Here, we propose a new method for driving amplitude-adjustable multiple RF ion trap electrodes. By dividing the output of the helical resonator into multiple circuits and simultaneously driving the ion trap multi-RF electrodes, each circuit is composed of capacitors connected in series, and the desired amplitude is applied to the ion trap RF electrodes using capacitive voltage dividing. In contrast, the capacitance of the multi-RF capacitors connected in series is determined by three constraints. Different voltages for each circuit are realized while keeping the phase consistent. Both the circuit simulation and analog simulations have been adopted to demonstrate the validity of proposed method, which has significant potential to be applied in the ion trap structure of multiplexed RF electrodes and contributing to the realization of ion trap-based quantum information processing.</p>
