| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 96 === This Thesis presents a fully integrated 2.4/5.2-GHz dual-band low-noise amplifier (LNA) / mixer for implantable biotelemetry application. By using conjugation matching, this front-end receiver circuit integrates LNA output and mixer input for single chip at the 2.4GHz and 5.2GHz frequency band. The front-end circuit exhibits a 2.2dB gain, a 15.5dB noise figure, IP1dB of -14.4dBm, and IIP3 of -0.5dBm at the 2.4GHz frequency band. The front-end circuit exhibits a 5.6dB gain, a 10.8dB noise figure, IP1dB of -15.5dBm and IIP3 of -6dBm at the 5.2GHz frequency band. This circuit exhibits a power consumption of 8.28mW from a 1.8-V supply. To achieve single chip design target, this chip input was designed without any off-chip matching component. The circuit exhibits S11 of more than 10dB at the 2.4GHz and 5.2GHz frequency. The front-end circuit was designed for operation frequency. By switching local oscillator (LO) frequency, we can achieve an output application at the 400MHz frequency. The chip has fabricated in a TSMC 0.18-μm CMOS technology. Moreover, the measurement and comparison with simulation had been done.
