Co-simulation of RFIC with bondwire antenna via retarded PEEC method

We present an antenna modeling method based on partial element equivalent circuit (PEEC) theory. The antenna is modeled as an equivalent circuit of lumped circuit elements, which enables circuit co-simulation between the antenna and circuits in both time and frequency domains. Antenna radiation is captured as an equivalent radiation resistor. For verification, a 2.4-GHz transmitter with bondwire antenna was implemented in a standard digital 0.35μm CMOS technology. Measurement shows good agreement with the proposed model. This model can be applied to any other on-chip electromagnetic structures. © 2012 IEEE.published_or_final_versio
