A Mixed-Mode Simulation Technique for the Analysis of RF Circuits Driven By Modulated Signals
نویسندگان
چکیده
This paper describes a new simulation technique of nonlinear RF circuits driven by modulated signals. Based on a true mixed-mode algorithm, it allows time-domain transient analysis of the envelope, while handling the carrier behavior in frequency-domain. Being similar in scope to the previously reported Envelope Transient Harmonic Balance [1]-[3], it is not limited, though, in excitation bandwidth.

Modeling and Simulation of Substrate Noise in Mixed-Signal Circuits Applied to a Special VCO
The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...
متن کاملOutput-Conductance Transition-Free Method for Improving Radio-Frequency Linearity of SOI MOSFET Circuits
In this article, a novel concept is introduced to improve the radio frequency (RF) linearity of partially-depleted (PD) silicon-on-insulator (SOI) MOSFET circuits. The transition due to the non-zero body resistance (RBody) in output conductance of PD SOI devices leads to linearity degradation. A relation for RBody is defined to eliminate the transition and a method to obtain transition-free c...
