A 2.4 GHz Wireless Transmitter Front-End for Endoscopy Capsule System

摘要：

A 2.4 GHz wireless transmitter front-end for the endoscopy capsule system is presented. The transmitter frontend consists of an IF module(ASK modulator,FSK modulator) and a direct-conversion transmitter rF front-end (double-balanced up-converter,power amplifier). The power amplifier (PA) has digitally programmable output power levels and works at 3.3V power supply, while other parts work at 1.8V power supply. The transmitter front-end is implemented in UMC 0.18um CMOS process.Its maximum out power to 50Ω load achieves 10 dBm with the data rate of 2Mbps and dissipates 7.09mA current from 1.8V power supply and 25mA from 3.3 V power supply.
