This article introduces a chip-scale ultralow-power atomic clock (ULPAC) in the microwave frequency region. A new suspended quantum package architecture along with a fully integrated frequency probing and locking loop implemented in CMOS technology r

A gate drive circuit for power devices requires a signal and power transmission function. The wires of the gate drive circuit tend to increase in circuits depending on a number of power devices. This paper proposes a gate drive circuit using SAW devi

To increase the electrical power transmission of surface acoustic wave (SAW) filters for gate drive systems of power conversion circuits, we fabricated unidirectional SAW filters based on a SiO2/Al/Pt/LiNbO3 structure in the frequency range of 380–

We propose a model to reduce the influence that the light-shift induced frequency drift has on the long-term stability of coherent population trapping (CPT)-based low-power atomic clocks. We experimentally validated the proposed model using the chip-

We developed a simulator that calculates the CPT resonances of all the energy levels of the Cs-Di line. The simulator can analyze the CPT resonances of not only the clock transition but also all the Zeeman sub-levels. To verify this calculation resul

To improve the power durability of interdigital transducer (IDT) electrodes, transversal type of surface acoustic wave (SAW) filters based on a SiO 2 /Al/LiNbO 3 structure were fabricated and their power durability, withstand voltage, and frequency t
