We present an alternative scheme for determining the frequencies of cesium (Cs) atom 6S-8S Doppler-free transitions. With the use of a single electro-optical crystal, we simultaneously narrow the laser linewidth, lock the laser frequency, and resolve a narrow spectrum point by point. The error budget for this scheme is presented, and we prove that the(More)
With 3D stacking design, high-performance low-power complex design is practical. However, due to the high design costs and extensive design efforts, 3D technology is not broadly adopted. For 3D stacking designs, most chip failures are due to power supply problems of voltage drop and noisy voltage. A feasible low-cost 3D stacking design method is proposed.(More)
