| dc.description.abstract | This thesis distribute into two parts. The first part of the thesis is the development of 2.5Gbps laser driver in a UMC 0.18µm CMOS process. The design of 2.5Gbps laser driver circuit includes a 2.5Gbps laser driver and a 2.5Gbps low voltage differential signals laser driver. The second part of the thesis is the development of 2.4/5.2GHz dual-band RF receiver in a tsmc 0.18µm CMOS process. The design of CMOS RF receiver circuit includes a 2.4/5.2GHz dual-band low noise amplifier and 5.2GHz micromixer.
The chip is on-chip measurement in first part. The 2.5Gbps laser driver exhibits a data rate of 3Gbps, modulation current of 34mA, gain of 10dB, output return loss smaller than -10dB and maximum output voltage swing of 0.85 Vpp. The 2.5Gbps low voltage differential signals laser driver exhibits a maximum data rate of 5Gbps, modulation current of 3mA, gain of 11.5dB, input and output return loss smaller than -10dB and maximum output voltage swing of 0.1 Vpp.
The 2.4/5.2GHz dual-band low noise amplifier is using the method of bonding die to printed circuit board. The 2.4/5.2GHz dual-band low noise amplifier exhibits a linear gain of 5.03dB, input return loss of 5.68dB and output return loss of 10.95dB at 2.4GHz, and a linear gain of 4.27dB, input return loss of 5.32dB and output return loss of 25.41dB at 5.2GHz. The 5.2GHz micromixer is using the method of on-chip. The 5.2GHz micromixer exhibits a conversion gain of 4.95dB, input 1dB compression point of -8dBm, output third-order inter-modulation intercept point of -5dBm, input third-order inter-modulation intercept point of -3dBm, local oscillator to radio frequency isolation of 32.78dB, local oscillator to intermediate frequency isolation of 26.27dB, radio frequency to intermediate frequency isolation of 22.56dB. | en_US |
