“…Microwave circuits containing semiconductor devices are generally considered to be a hybrid system and can be simulated using a field-circuit hybrid method based on equivalent sources [22]. Generally, the equivalent sources first equate the electromagnetic field effect on the semiconductor devices as lumped circuits, and then solves the circuits formed by the connection between the equivalent source and the lumped circuit, finally converting the obtained voltage or current to the electric or magnetic field value.…”

This work analyzes the temperature effects on microwave circuits by employing a novel field-circuit hybrid multiphysics simulation. Firstly, the multiphysics simulation is implemented by solving the coupled governing equations including Poisson equations, semiconductor transport equations, and thermodynamic equations; then, the multiphysics simulation is incorporated into circuit analysis; finally, the circuit simulation results are integrated into the finite-difference time-domain (FDTD) simulation by equivalent sources. In this manner, a field-circuit hybrid multiphysics simulation method is presented. Taking two different microwave rectifiers operating at S- and C-band as examples, temperature effects are analyzed by the proposed approach. Simulation results are in good agreement with measured values, demonstrating the accuracy and applicability of the proposed approach. The presented method more suitably reveals the temperature effects on the rectifier.

“…For example, it is mentioned in the literature that the simulation of a simple circuit containing a PIN diode using ADS at 20 MHz did not show the phenomenon of "punch-through" current, which is not consistent with experiments [10]. Among the available techniques, a hybrid solver that combines the capabilities of a physicsbased simulation and a full-wave analysis has attracted researchers' interest, particularly because of its ability to account for the presence of lumped components in a distributed circuit [10][11][12][13][14][15][16]. This is based on semiconductor device physical models, rather than equivalent models, and solves field equations such as the Maxwell equations, semiconductor transport equations, and thermodynamics equations, to model the electromagnetic wave propagation and charge transport with the temperature effects inside semiconductor devices.…”

Embracing the era of higher operating frequencies, expanding functionality, and increased integration scale, modern circuit design relies more and more on the accurate prediction of the electromagnetic (EM) effects resulting from undesired radiation and mutual coupling of digital electronic devices. In this paper, an electromagnetic-physics-based simulation method is proposed, to simulate semiconductor devices and circuits. It utilizes physics-based simulation to analyze semiconductor devices in a circuit and incorporates this physics-based simulation into electromagnetic simulation (e.g., the finite difference time domain (FDTD)), to simulate a circuit at high frequency. To validate the proposed method, sample numerical results on circuits containing a commercial p-i-n diode with model number mot_bal99lt1 at radio frequency (RF) were obtained and compared with measurement data. The comparison showed a good agreement between the two sets of data, which validated the feasibility and accuracy of the proposed algorithm. Moreover, the proposed method can provide a useful physical mechanism for understanding effects on semiconductor devices and circuits.
