An up-conversion mixer implemented in a 0.35μm SiGe BiCMOS technology for a double conversion cable TV tuner is described, The mixer converts the 100MHz to 1000MHz band to the Intermediate Frequency of 1GHz above. Th...
We analyze a wide-band,high-linearity down-conversion mixer for cable receptions that is implemented in 0. 35μm SiGe BiCMOS technology. The bandwidth of the RF (radio frequency) input covers the range from 1 to 1.8...
This paper presents an LC VCO with auto-amplitude control (AAC), in which pMOS FETs are used,and the varactors are directly connected to ground to widen the linear range of Kvco. The AAC circuitry adds little noise ...
We present the design of a wide-band low-noise amplifier (LNA) implemented in 0.35μm SiGe BiCMOS technology for cable and terrestrial tuner applications. The LNA utilizes current injection to achieve high linearity...
A DC-offset cancellation scheme in a 5GHz direct-conversion receiver compliant with the IEEE 802.11a wireless LAN standard is presented. An analog feedback loop is used to eliminate the DC-offset at the output of the....
