A 600-V Peak-to-Peak 65-dBc RF Signal Source for Trapped-Ion Quantum Computing

Abstract

This brief presents a high-voltage RF source for trapped-ion quantum computing. It consists of an external transformer and a driver implemented on a single chip. The use of a transformer significantly reduces on-chip current driving requirements to 32mA while delivering a 620-VPP to the output. The proposed architecture also achieves a 20dB improvement in SFDR compared to the previous work. This brief includes a guide for the optimal transformer design that can maximize the output voltage with the minimum power consumption. The proposed design scheme provides a miniaturized implementation of the RF source and makes it promising for scalable quantum computing with multiple RF sources.
