| dc.description | This work presents a VCO in the -Gm LC configuration, that operates in the range of 1.3 up to 1.8GHz, followed by amplifiers in the cascode configuration connected to the output. This concept is used with the intention to increase the isolation and inhibits the effects provoked by the impedance mismatches, which depend on the inner and outer agents to the chip. The solution in question inhibits the effects provoked by one of the inner causes of the impedances mismatch, which is the connection with other circuits that are part of a determined system. For the front-ends, the connections with the mixers must be observed with attention, because the VSWR (Voltage Standing Wave Ratio) values, presented by these circuits are high and are between 2.5 and 4.8 in this frequency band. The impedances mismatch effects, caused by wires in the encapsulations assemblies, and in the chip on board, arranged with the output loads are also much minimized to the oscillators, with the amplifiers use in the cascode configuration. The RFIC (Radio Frequency Integrated Circuit) was implemented on SiGe BiCMOS .35m technology from AMS (Austria Microsystems) foundry. Copyright 2007 ACM. | |
