Before an IC chip enters the tape-out phase, engineers must prepare extensively to ensure the smooth progress of subsequent stages, and a reasonable layout design is key to ensuring chip performance, reliability, and cost-effectiveness. 1. Pin Layout Optimization Clearly define the direction and position of the pins, especially keeping the clock pins and analog signal … Read more
In the critical stage of integrated circuit (IC) design before tape-out, the routing layout becomes a crucial factor in determining the chip’s performance, power consumption, and reliability. A reasonable routing strategy not only optimizes signal integrity but also effectively reduces noise interference, ensuring the correct implementation of chip functions. 1. Control Wire Length and Enhance … Read more
Introduction This article uses a synchronous step-down converter power IC in an SOP-8 package as an example to introduce the PCB design for power supplies. Related Parameters As mentioned in “Guidelines for PCB Design of DC/DC Switching Power Supplies: Part One”, it is essential to understand the related parameters before starting the design, as shown … Read more
