Niknejad Berkeley Wireless Research Center‚ Dept. of EECS‚ UC Berkeley‚ Berkeley‚ CA 94704‚ USA Abstract— This paper reports two 11 GHz low-noise amplifiers (LNA) in 0.18µm CMOS technology. A cascade two stage LNA achieves 12 dB of power gain‚ 3.5 dB of noise figure‚ and an input/output match of −15 dB/−27 dB at 11GHz‚ while consuming 28mA from 1.8V supply. The second LNA is a modified

Queries that consist of several operations have many more evaluation options‚ and finding a good plan represents a significant challenge. A more detailed view of the query optimization and execution layer in the DBMS architecture presented in Section 1.8 is shown in Figure 13.1. Queries are parsed and then presented
