This paper proposes a system in package (SiP) for ultrasonic ranging composed of a 4 × 8 matrix of piezoelectric micromachined ultrasonic transducers (PMUT) and an interface integrated circuit (IC). The PMUT matrix is fabricated using the PiezoMUMPS process and the IC is implemented in the AMS 0.35 µm technology. Simulation results for the PMUT are compared to the measurement results, and an equivalent circuit has been derived to allow a better approximation of the load of the PMUT on the IC. The control circuit is composed of a high-voltage pulser to drive the PMUT for transmission and of a transimpedance amplifier to amplify the received echo. The working frequency of the system is 1.5 MHz.

By doing research on the optical characteristics of TFEL panel, a driver circuit controlled by Field-Programmable Gate Array(FPGA) is designed. This design adopts an unsymmetrical way to lighten the panel which is different from the custom symmetrical hybrids. The availability of this unsymmetrical structure improves the stability when the system is on the high-voltage condition, prolongs the service life of the driver circuit, and significantly reduces the costs of a TFEL display system.
