چکیده
A 45MHz-2.5GHz broadband CMOS up-conversion mixer implemented in a conventional 0.18µm technology is presented this letter. The offered employs bisymmetric class-AB input stage order to provide high linearity and match the IF impedance over 0.3-20.15MHz frequency range. draws 3mA current from 1.8V supply voltage, core chip dimension of 0.05*0.08mm2. At range 45MHz-2.5GHz, output third-order intercept point (OIP3) larger than 9dBm, LO-RF isolation characteristic less -60dB, maximum conversion gain 5.21dB. achieves minimum noise figure 8.42dB.

The MICROMIXER: A Highly Linear Variant of the Gilbert Mixer Using a Bisymmetric Class-AB Input Stage
This paper outlines the basic theory of a development of the Gilbert mixer. The bipolar junction transistor (BJT) differential pair widely used as the RF input stage is replaced by a bisymmetric Class-AB topology based on translinear principles. It does not have inherent gain compression, affording a greatly extended signal capacity. The linearity of variants of the basic form is excellent, pro...

In this paper, a low-power up-conversion current-mode mixer, designed in the chartered 0.18-μm RFCMOS technology, is proposed to realize the transmitter front-end in the frequency band of 2.4 GHz. The proposed mixer can convert a 10 MHz intermediate frequency (IF) signal to a 2.4 GHz RF signal, with a local oscillator power of 2 dBm at 2.39 GHz. A comparison with conventional voltage-mode up-co...

This paper presents a low-voltage low-power differential linear transconductor with near rail-to-rail input swing. Based on the current-mirror OTA topology, the proposed transconductor combines the Flipped Voltage Follower (FVF) technique to linearize the transconductor behavior that leads to classAB linear operation and the virtual transistor technique to lower the effective threshold voltages...
متن کاملA 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 ...
