Abstract :
A multipurpose TV tuner front-end implemented in 0.35μm BiCMOS technology is presented. It employs a dual-conversion topology and a fully integrated RF automatic gain control loop. The tuner front-end achieves -68dB composite-triple beat (CTB) distortion and a noise figure of 6.8-7.4dB in a 50-870Mhz input frequency range. In addition, the front-end is interfaced with a companion chip, which contains a high dynamic range ADC combined with programmable digital filters to accommodate multi-standard operation.
