design techniques of rfic transreceiver

Due to the integration capabilities of CMOS technology, RF transceiver architectures have markedly departed from the conventional heterodyne approach, including far greater on-chip complexity in favor of minimizing the number of external components.
• High-resolution low-power analog-to-digital converters employing new methods of improving the dynamic range have emerged as an integral part of transceivers.
• Numerous low-voltage low-noise RF and baseband circuit techniques have been invented that circumvent the limitations of MOS transistors.
• Extensive research on passive monolithic devices such as inductors and varactors has led to accurate models and hence ease of use in circuit design.
