A scalable Gummel-Poon model for high-speed SiGe HBTs is developed based on Gummel-Poon model in this paper. This model is well applied to simulation software of ADS and Hspice. The scaling is mainly based on different physical dimension of individual devices, all the scaling parameters in the scaling equations are extracted directly from the measurement data of various dimension. The correctness...
An even harmonic mixer (EHM) with a resonant circuit is designed in this paper. The proposed mixer employs a current reuse circuit in the RF input stage to improve its linearity and conversion gain, and uses the double frequency technique in the LO input stage, respectively. In addition, the proposed topology also has the advantages of low power consumption. The simulated results reveal that the proposed...
