The design of transformers, a key component radio frequency integrated circuits (RFICs), is traditionally carried out through an iterative process involving extensive electromagnetic simulations. While kits (PDKs) offer tools based on interpolation or fitting equations to simplify parameter estimation, these are restricted standard geometries, leaving designers manually simulate and optimize custom designs. This approach inefficient resource intensive. paper proposes automated generate...
