In the information age, the need for larger data, hence the need for higher data rates is ever-growing. To satisfy higher data rates, higher bandwidths of frequencies are required and realizing high bandwidth transceiver (transmitter/receiver) circuits is not always trivial. Widely used approach on designing high bandwidth (Δf) transceiver circuits is to increase the operation frequency (f0) such that the fractional bandwidth (Δf/f0) is relatively small, which makes the design of transceiver circuits more realizable. Hence, as the data-rate requirements increase, the operation frequencies of front-end RF circuits also increase and with mmWave 5G, the frequency of operation goes up and beyond 30 GHz. With the increased frequency, the parasitics coming from the layout of a circuit become much more significant. Hence, for circuit optimization, EM based simulation methods should be applied. However, simulating the whole circuit in EM simulators may take too much of design time. Hence, separating the core including the transistors and lower level metals from the rest of the design and simulating them separately is recently adapted. However, if these cores are not defined and simulated properly, there might be inaccuracies of the simulation results, or the simulations may take more time than needed. Hence, the focus of this thesis is to systematically define the cores up to three different metal levels and simulate them using two different methods, namely parasitic extraction and EM simulation, so that the tradeoff between accuracy and simulation times can be determined and proper design method can be established. The results will pave the way of faster and accurate design and optimization procedures, improving design efficiency.
