This paper presents a design procedure that involves incorporating the parasitics into the design of a transformer based Matching Network(MN). In this work, flip-chip based integration is opted to connect the on-chip blocks to the external circuitry. At mm-Wave range, parasitics from the bump, ESD and metal traces play a vital role in altering the desired performance of MN. The inductance and capacitance contributed by the ESD structure and the flip-chip bump are extracted from EM simulations which are embedded into the design. This optimization process requires multiple trails which is addressed by SKILL code based spiral inductor layout generation. The MN designed in 28nm CMOS converts a 50Ω load to 4 + 5.1j for a mm-Wave DAC functioning at 28GHz.
