Mixers Figure 7.28 Plot of image rejection versus phase and amplitude mismatch. 7.11 Alternative Mixer Designs In the following section, some variations of mixers will be mentioned briefly, including the Moore mixer, which rejects image noise from a degeneration resistor, mixers that make use of inductors and transformers, and some other low-voltage mixers. 227
228 Radio Frequency Integrated Circuit Design Figure 7.29 Three-dimensional plot of image rejection versus phase and amplitude mismatch. 7.11.1 The Moore Mixer In a receiver, the noise produced by the mixer is sometimes very important. If the mixer is to use resistive degeneration and it is to have its phase shifts in the IF and LO paths, then there is a way to interleave the mixers, as shown in Figure 7.30, such that the noise produced by the degeneration resistors R E is also image rejected. Here, the noise due to these resistors is fed into both paths of the mixer rather than just one; thus, it gets image rejected, and its effect is reduced by 3 dB. Since noise due to degeneration resistors is often very important, this can have a beneficial effect on the noise figure of the mixer. 7.11.2 Mixers with Transformer Input Figure 7.31 shows a mixer with a transformer-coupled input and output [2]. Such a mixer has the potential to be highly linear, since a transformer is used in place of the input transistors. In addition, this mixer can operate from a low power supply voltage, since the number of stacked transistors is reduced compared to that of a conventional mixer. We note that for a downconversion mixer, the input transformer could be on-chip, but for low IF, the output transformer would have to be off-chip.
