  • Low-voltage, low-noise power supply reference design for ultrasound front-ends

    This reference design is a power supply optimized specifically for powering eight 16-channel receive AFE ICs in ultrasound imaging systems. This design uses a single-chip DC/DC converter + LDO combo regulator to set each LDO input just above the dropout voltage while fully utilizing the LDO PSRR, thereby reducing parts count while maximizing efficiency. In addition, ultra-low noise LDOs help achieve the highest possible analog-to-digital conversion resolution, resulting in higher image quality. The design's ability to synchronize the switching frequency with the master clock frequency and the system clock frequency allows system designers to apply simple filtering techniques to eliminate power switching noise on ground loops or use spread spectrum clocking to reduce EMI. Additionally, the design implements an electronic fuse device, providing a simple and flexible method of overcurrent protection.

A system basis chip (SBC) is an integrated circuit (IC) that combines several typical building blocks of a system, including transceivers, linear regulators, and switching regulators. While these integrated devices can provide size and cost savings in many applications, integrated devices do not work well in every situation. For applications that are less suitable for using an SBC, a better approach is to build discrete implementations of the above building blocks to create a discrete SBC.
