A CMOS active mixer based on voltage control load technique which can operate at 1.0 V supply voltage was proposed, and its operation principle, noise and linearity analysis were also presented. Contrary to the conventional Gilbert-type mixer which is based on RF current-commutating, the load impedance in this proposed mixer is controlled by the LO signal, and it has only two stacked transistors at each branch which is suitable for low voltage applications. The mixer was designed and fabricated in 0.18 μm CMOS process for 2.4 GHz ISM band applications. With an input of 2.44 GHz RF signal and 2.442 GHz LO signal, the measurement specifications of the proposed mixer are: the conversion gain (G C ) is 5.3 dB, the input-referred third-order intercept point (P IIP3 ) is 4.6 dBm, the input-referred 1 dB compression point (P 1dB ) is −7.4 dBm, and the single-sideband noise figure (N FSSB ) is 21.7 dB.

“…These characteristics are especially critical in mobile wireless communication systems due to the limitation of battery capacity. With the reducing scale of CMOS technologies, the key problem of migration to advanced CMOS technologies comes from continual reduction in supply voltages, resulting in poor performance in analog and RF circuits [1,2]. Insufficient voltage headroom results in some circuit topologies unable to satisfy the required specifications or even unable to operate.…”

“…The Gilbert-type mixer is the most mature mixer architecture widely used as the down-converter in CMOS superheterodyne receiver. Due to large number of stacked transistors at a low voltage supply and the voltage drops across the load resistors, the switching transistors and the transconductance stage of the mixer become critical, so this architecture cannot be used in CMOS advanced technologies which work with low supply voltage below 1 V [1,2]. To reduce the supply voltages, some folded mixer architectures have been investigated in [2,3] and [6], but they still have some drawbacks: insufficient linearity under low supply voltage and/or additional inductors increasing area occupation.…”

A CMOS active mixer based on variable load technique which can operate at 1.0 V supply voltage is proposed and its operation principle is presented. The proposed mixer controls the load impedance according to the LO signal. It has only two stacked transistors at each branch, which is suitable for low-voltage applications. The mixer was designed in 0.18-μm CMOS process and measured in 2.4-GHz ISM band. With a 2.440 GHz RF input signal and a 2.442 GHz LO signal (4 dBm), the conversion gain is 5.3 dB, the input-referred third-order intercept point is 4.6 dBm, the input-referred 1-dB compression point is −7.4 dBm, and the single-sideband noise figure is 21.7 dB. Current consumption is 3.5 mA at 1.0 V supply. Keywords: CMOS active mixer, variable load technique, low-voltage Classification: Integrated circuits References
