摘要

Wireless communication and its application have been growing rapidly in recent years. With the recent advances in CMOS technology, Radio Frequency CMOS IC design provides a potential solution for System-On-Chip. This dissertation explores the design of a fully integrated CMOS Low-Noise Amplifier for an IEEE 802.11a wireless communication receiver. A new design methodology is presented for optimization of feedback to achieve simultaneous noise and gain match. Two-port noise theory is extended to multi-port noise analysis for a three-port-to-two-port noise transformation. This approach is applied in the design of a 5.3-GHz LNA in a CMOS 0.18-um technology. The measurement gives a nominal forward gain of 5.2 dB, input and output impedance matching of -9.3 dB and -8.9 dB respectively, isolation of -42.8 dB, estimated noise figure of 4.8 dB with the circuit drawing 4.2-mA from a 1.5-V supply. A novel process-variation insensitive network is proposed to realize the on-chip impedance matching that minimizes the effect of process variation. The proposed network utilizes precision matching capacitors to achieve a low sensitivity to process variation. Its performance is demonstrated by Monte Carlo simulations.
