Abstract:	摘要： This paper proposes a microwatt source-driven down-conversion mixer with broadband asymmetrical broadside-coupled baluns in a 90-nm CMOS low-power process. The forward body biased (FBB) technique reduces the threshold voltage [Formula Omitted] and supply voltage for operation in the near weak inversion region in millimeter-wave mixer designs. To effectively reduce the size of the chip, an asymmetrical broadside-coupled balun is developed with a bandwidth of 103 GHz (from 34 to 137 GHz) with a low insertion loss of 3.66 dB (3 dB for an ideal balun) at 58 GHz. The chip area of the balun is [Formula Omitted]. The proposed FBB mixer has a 4.2-dB peak conversion gain and a 14.3-dBm input third-order intercept point at 55 GHz under a 2-dBm local-oscillator power. The dc power of the FBB mixer core is only [Formula Omitted], while it draws a [Formula Omitted] dc current from a 0.5-V supply. The fabricated FBB mixer, comprising two asymmetrical broadside-coupled baluns, and all of test pads and dummy blocks, occupies an area of [Formula Omitted]. An [Formula Omitted] that is obtained using the ultra-low power consumption FBB mixer is as high as 23.4. 出版者： New York: The Institute of Electrical and Electronics Engineers, Inc.
