We present an efficient implementation of an approximate balanced truncation model reduction technique for general large-scale RLC systems, described by a state-space model where the "C" matrix in the time-domain modified nodal analysis (MNA) circuit equation "C\dot{x}=-Gx+Bu" is not necessarily invertible. The large sizes of the models that we consider(More)
We present a framework for passivity-preserving model reduction for RLC systems that includes, as a special case, the well-known PRIMA model reduction algorithm. This framework provides a new interpretation for PRIMA, and offers a qualitative explanation as to why PRIMA performs remarkably well in practice. In addition, the framework enables the derivation(More)
