A Si/SiGe BiCMOS Mixer with 3rd-Order Nonlinearity Cancellation for WCDMA Applications (Student Paper)
نویسندگان
چکیده
This paper presents a general analysis of the 3rd-order nonlinearity of a differential common-emitter (CE) radio frequency (RF) amplifier and a novel way to cancel the 3rd-order nonlinearity. A SiGe BiCMOS mixer is designed based on the 3rd-order cancellation scheme. The mixer achieves +6dBm IIP3, 15dB gain and 7.7dB NF with only 2.2mA current at 2.1GHz. This performance substantially exceeds that of previously reported active mixers in this frequency range.
