On the other hand, imbalance at the base influences the CG mostly. The results show that the imbalance at the collectors of the transistors has the most severe impact on the differential output amplitudes and phases. An imbalance analysis is therefore carried out to understand the critical layout routings. At this frequency, an underlying asymmetrical layout of the switching quad leads to several problems such as output amplitude difference, phase difference deviating from 180°, and conversion gain (CG) degradation. This paper presents a fully-differential bootstrapped Gilbert-cell-based frequency doubler designed in a 130-nm SiGe process to provide an output frequency of 220 GHz. Influence of Amplitude and Phase Imbalance on a Y-band Bootstrapped Frequency Doubler using 130-nm SiGe Technology In this work we show that ENOP-based divider controllers offer strong mitigation of both wandering and horn spurs. Among those, the ENOP DDSMs are worthy of notice because of their performance in terms of nonlinearity-induced noise and spurs. Different families of DDSMs have been presented in the past which represent an alternative to MASH-DDSMs. A type of time-varying spurs and another type of fixed sub-fractional frequency spurs, denoted wandering spurs and horn spurs, respectively, have been observed in simulations and measurements of fractional-N frequency synthesizers with a MASH-based divider controller. The DDSM can contribute significantly on the phase noise and spur pattern in the output of a nonlinear synthesizer. The divider controllers in fractional-N frequency synthesizers are typically digital ΔΣ modulators (DDSMs).

(Please refer to the Cadence Virtuoso Multi-Mode Simulation datasheet for more details on other Virtuoso Spectre Circuit Simulator L and XL capabilities). Additionally, the Virtuoso Spectre RF Simulation Option is now included in the Cadence Virtuoso Spectre Circuit Simulator XL. It offers a frequency-domain harmonic balance engine for faster and more accurate simulation of high dynamic-range, weakly non-linear RF circuits, and it uses a patented time domain shooting algorithm optimized for highly non-linear circuits. Virtuoso Spectre Simulator XL includes the only RF simulator that addresses the needs of the entire RF design spectrum.
