Abstract :
The design and analysis of down-conversion mixer for high-band applications between 6-15GHz is presented in this paper. The mixer proposed is based on folded double-balanced Gilbert cell topology which is good for low-voltage use and well-balanced performances. Two on-chip inductors are introduced for biasing and reducing flicker noise. By setting the bias separately, both the LO stages and trans-conductance stages have difference current. The simulation in TSMC 0.13-μm process shows a conversion gain of 2.3-4.2dB, a noise figure of 12.9-15.5dB, and a third-order inter-modulation intercept point (ΠP3) of 5.1-6dBm between 6-15GHz. This mixer consumes 4.8mW under a 1.2-V supply, and the total area of the layout is 0.6 × 0.8mm2.
