  • Pseudo-differential pair is widely used in band-pass RF amplifiers. For CMOS process, it has been proven that the linearity of a pseudo-differential amplifier outruns that of a differential-pair amplifier. However, for SiGe HBT devices, few analysis has been done.

    In this thesis, a differential and a pseudo-differential RF amplifier will be first designed in 0.13-µm SiGe BiCMOS process. Then, key matrics such as AM-AM, AM-PM, IMD3 and PAE should be compared. In addition, a theoretical analysis on the nonlinearity is encouraged to be done.

    Tasks:

    -Circuit desgin and simulation with Cadence SpectreRF or Keysight ADS

    -Parasitics extraction using QRC and EM simulation using Momentum

    -Layout in Cadence Virtuoso (DRC, LVS check)
