In this paper, a wide-band low noise amplifier, two mixers and a VCO with its buffers implemented in 50GHz 0.35mum SiGe BiCMOS technology for dual-conversion digital TV tuner front-end is presented. The LNA and up-converting mixer utilizes current injection technology to achieve high linearity. Without using inductors, the LNA achieves 0.1-1GHz wide bandwidth and 18.8-dB gain with less than 1.4-dB...
The wideband high-linearity mixers for a double conversion cable TV tuner is presented. The up-conversion mixer converts the input signal from 100 MHz to 1000 MHz to the intermediate frequency (IF) of 1 GHz above. And the down-conversion mixer converts the frequency back. The degeneration resistors are used to improve the linearity. The tuner is implemented in a 0.35 mum SiGe technology. Input power...
This paper represents a LC VCO with AAC (auto amplitude control), in which PMOS FETs are used as active components, and the varactors are directly connected to ground to widen Kvco linear range. The AAC circuitry adds little noise to the VCO and provides it with robust performance over a wide temperature and carrier frequency range. The VCO is fabricated in 50-GHz 0.35-mum SiGe BiCMOS process. The...
