A Flicker-Noise-Free DC-Offset-Free Harmonic Mixer in a CMOS Process
نویسندگان
چکیده
A harmonic mixer for direct-conversion receivers is proposed and fabricated in a CMOS process. It is immune from both the flicker noise and self-mixing induced DC offset. Using the lateral bipolar transistor and the harmonic mixing technique, it achieves +15dB gain, 17.8dB NF at 10kHz frequency, 8.2dBm IIP3, +44dBm IIP2 and more than 30dB DC offset suppression. It consumes 2.2mW power at 3V.

A 900MHz CMOS Balanced Harmonic Mixer for Direct Conversion Receivers
A 900MHz balanced harmonic mixer for direct conversion receivers is fabricated in a 0.35 μm standard digital CMOS process. The self-mixing-induced DC offset is about 44dB lower than that of the conventional mixer. The inputreferred offset is reduced to the noise level. Specific techniques on flicker noise reduction are also discussed. At 3V power supply and -15.4dBm LO power, it achieves 13 dB ...
متن کاملStudy of Flicker Noise for Zero-IF Receiver
Zero-IF receiver has some advantages, such as small factor, low cost and easily integrated on a chip. They make it competitive of RF receivers. However, DC Offset and flicker noise, etc., have profound effects in zero-IF receiver, which need not be considered in super-heterodyne receiver. Following a major study of flicker noise, possible solutions are given, especially those based on the passi...

This paper reports on a fully-integrated CMOS switchable directconversion receiver for 2GHz and 5GHz. Switchable low noise amplifier is proposed for suiting for multiband (2GHz, 5GHz). Sub-harmonic mixing is used for down-conversion to minimize the DC-offset due to LO-leakage. The residual DC-offset is cancelled by a digital-to-analog converter at the output of mixer. For quadrature down-conver...
متن کاملNested Chopper Stabilization in Analog Multipliers and Mixers by Philip Godoy
We describe a general offset-cancelling architecture for analog multiplication using chopper stabilization. Chopping is used to modulate the offset away the output signal where it can be easily filtered out, providing continuous offset reduction which is insensitive to drift. Both square wave chopping and chopping with orthogonal spreading codes are tested and shown to reduce the offset down to...
