A high performance W-band LNA is designed in 0.13 µm SiGe BiCMOS technology by firstly deploying SC-GCPW input matching network, shielded cascode stage and partition layout. Noise figure of the LNA, parasitic coupling of the cascode stage and reverse isolation are considerably reduced. The LNA achieved a measured gain of above 45 dB, noise figure of 7.2 dB at 95 GHz and 19 mW power consumption in 0.13 µm BiCMOS which is the state-of-the-art on silicon. This LNA performance could help the W-band total power radiometer obtain a 0.5-K NE¨T.

Abstract. In this paper, a fast pin assignment optimization method is proposed for improving signal integrity performance of VLSI package. This performance is evaluated by two cost function. Some other methods based on heuristic algorithm can find a good solution for pin assignment problem. Since the solution space is of high dimension, those algorithms require a large time consumption. The proposed pin assignment construction method is guided by the prior knowledge about the optimal solution of pin assignment. It generates a solution by directed construction. Experimental results show that the quality of solution produced by proposed method is better than that by heuristic algorithm and the time consumption is practically negligible.
