Abstract: |
The design and simulation of an
integrated common mode filter (CMF) for differential data lines, like the USB
2.0 interface, is presented in this paper. The device is
manufactured in a bipolar semiconductor process for the integration of diodes
protecting sensitive CMOS circuits against damage by Electrostatic Discharge
(ESD). The filter is formed by planar coupled
coils that are processed in copper/polyimide layers applied on top of silicon
die. The design process is using 2.5D simulation techniques based on method
of moments. Furthermore a lumped model is derived that allows exact and
efficient transient simulations in SPICE [1] based simulators. The filter design
itself shows strong common mode rejection in the GSM spectrum. The small size
(1.34 mm x 0.95 mm) of the device makes it well suited for integration in
modern mobile phone applications, to suppress electromagnetic interference
(EMI) between a USB transmitter and a GSM receiver. Measurement data
demonstrates the EMI protection in the GSM downlink spectrum. The dynamic
resistance of the ESD diodes is derived in transmission line puls (TLP)
measurements. |
