An amplitude shift keying transmitter and receiver chipset with low power consumption using 40nm CMOS technology for wireless communication systems is described, in which a maximum data rate of 10Gbps and power consumption of 98.4mW are obtained with a carrier frequency of 135GHz. A simple circuit and a modulation method to reduce power consumption are selected for the chipsets. To realize multi-gigabit wireless communication, the receiver is designed considering the group delay optimization. In the receiver design, the low-noise amplifier and detector are designed considering the total optimization of the gain and group delay in the millimeter-wave modulated signal region.
