ESD on High-Frequency RF Circuits

In our recent piece on board-level ESD protection, I noted that, while the board is protected during actual usage, chip-level ESD protection is focused more on what might happen to the chip during handling, before it’s inserted into its final board resting place.

Such chip-level ESD circuits are mostly standard, typically involving some kind of diode breakdown to shunt excess energy. But this is apparently a dicier deal with RF circuits, since plain vanilla ESD circuits can degrade the RF performance.

TSMC and imec recently worked on two alternatives to protect low-breakdown oxides in 60-GHz RF circuits. Both involve resonant circuits; one has two diodes, the other none – it essentially has a shunt inductor.

As reported, both circuits provide charged-device model protection with minimal disturbance to the RF specs – “minimal” meaning small enough to be considered not affected.

Silicon Lifecycle Management Paradigm Shift

Sponsored by Synopsys

An end-to-end platform solution, Silicon Lifecycle Management leverages existing, mature, world-class technologies within Synopsys. This exciting new concept will revolutionize the semiconductor industry and how we manage silicon design. For the first time, designers can look inside silicon chip devices from the moment the design is created to the point at which they end their life.

Configure the charge and discharge current separately in a reversible buck/boost regulator

Sponsored by Maxim Integrated (now part of Analog Devices)

The design of a front-end converter can be made less complicated when minimal extra current overhead is required for charging the supercapacitor. This application note explains how to configure the reversible buck/boost converter to achieve a lighter impact on the system during the charging phase. Setting the charge current requirement to the minimum amount keeps the discharge current availability intact.
