Abstract:
|
A novel way of manufacturing an on-chip
transformer that produces high inductance ratio (LSec/LPri > 30)
with excellent area efficiency is presented. This technique uses an
electrical all-round coupling effect of a conductor A (Primary
Coil), having large effective width, and a densely routed
conductor B (Secondary Coil). Thus, a high turn ratio monolithic
transformer, using minimum die size, is realizable on silicon. The
coil having the dense routing can also be doubled up as a
monolithic RF choke on silicon. In this work, area efficiency is
compared between various type of existing transformer structures
(i.e. Interleaved and Stacked transformer), based on unit
inductance. The method presented is fully compatible to all the foundry standard CMOS processes. |
