RF CMOS power mixer design for short range wireless applications with focus on polar modulation

摘要: This thesis work is a circuit design of RF CMOS power mixer that should be used for short range wireless applications, like Bluetooth. The also polar modulation technique.In communication systems, data transportation between nodes done by adjusting frequency, phase or amplitude characteristic sinusoidal carrier. In systems this performed with modulator.Today.s Bluetooth transmitters use quadrature modulators. modulator an alternative architecture can reduce current consumption, which particular importance in Bluetooth.The designed part the and converts incoming low frequency signal to high radio signal. implemented as Gilbert mixer, preferred design. variable gain control output fulfil specified targets. Schematic layout are using Cadence simulated SpectreRF. Infineon.s 0.13 im technology process C11N.Schematic simulations prove final functionality designed, reduces total consumption comparison today modulator.
