....mixers to produce the and components of the intermediate frequency (IF) signal. A tunable third order filter alters the transfer characteristic of the LNA to achieve further attenuation of the image signal. A PLL automatically tunes the image reject band of the filter to the image frequency [4] [6]. It is important to mention that the circuit implementations of the voltage controlled oscillator (VCO) and the filter are exactly the same. Because of this similarity, the locations of the pole and zero of the filter are closely related to the oscillation frequency of the VCO. The VCO and the ....

....by assuming that 2224 IEEE JOURNAL OF SOLID STATE CIRCUITS, VOL. 33, NO. 12, DECEMBER 1998 (a) b) Fig. 8. A simple gyrator and its equivalent circuit with noise sources. the largest acceptable signal voltage is a fixed parameter [19] often expressed as a simple fraction of the supply voltage [20]. One problem with such an approach is that it partly obscures the dependence of dynamic range on power consumption and choice of transconductor architecture. In previous work where the dynamic range is formulated explicitly without such assumptions, the analysis is typically limited to the ....
