Abstract
This dissertation demonstrates the design procedure of low power,
high IRR and highly attenuated blockers Quadraure Band-pass ~L
modulator in accordance with the Bluetooth standard. A linear models
implemented in MATLAB is used to examine the behavior of the
modulator in the presence of circuit imperfections.
A 0.13 urn CMOS technology is used to implement Quadrature
modulator in the transistor level. Simulation results show that the
Quadrature modulator achieves 76dB SNR for I MHz bandwidth. It
consumes 3.5mW from a 1.1V supply. A minimum image rejection ratio
of 56 dB is achieved.
Key words: low-if receiver, Quadrature Band-pass ~L modulator,
continuous time delta-sigma modulator, image rejection ratio, CMOS,
behavioral modeling.
