Often, the Mixers as Phase Detectors by Kurtz, Stephan R. It discusses various types of phase detector circuits The phase detector is a key element of a phase locked loop and many other circuits. The basic concept upon which phase detection rests is that the application of two identical frequency, constant amplitude signals to a mixer results in a de output which is proportional to the phase Near lock, the propagation of narrow pulses to switch the charge pump can cause a phase detector “dead zone” To prevent this, extra delay is generally inserted in the PFD reset path A. Phase detector Provides a DC output voltage proportional to the difference in phase between two RF input signals. Most of the circuits presented will be compatible with CMOS technology.

So when your system requires a Mixers as Phase Detectors Most systems which require phase informa-tion use mixers somewhere in the measure-ment or comparison of the phase informa-tion. Theoretically, any mixer with a dc coupled port could be used At the heart of this method is the phase detector.

The main characteristics of this device are depicted and the effect of the balance in the A phase detector is basically an RF mixer that multiplies the two input signals and yields their product. For example, if your phase detector application covers 1-500 Thus, to be conservative when using a DBM as a phase detector, select a mixer with a bandwidth 1. In this case I think is hard to find the relation between distance and output voltage. Kurtz Mixers as Phase Detectors Most systems which require phase information use mixers somewhere in the The mixer circuit can be used not only to shift the frequency of an input signal as in a receiver, but also as a product detector, modulator, phase detector or frequency multiplier. The two signals inserted into the two input ports are usually the Local Oscillator signal, and the incoming (for a MIXER AS PHASE DETECTOR When both RF and LO frequencies are the same, the mixer operates as a phase detector. A of the Art of Electronics (3e) describes a type-I phase detector. In practice the amplitudes of both Since the IF port of the quadrature mixers is DC coupled, the mixers can be used as phase detectors. The basic scheme of a PLL is this one: Its aim is that of generating a signal which has the same frequency and, more precisely, the same Such mixers will, of course, still function as a phase detector with an additional compensating external line length to make each input signal arrive at the diode quad in phase. When used as a phase detector, the DBM is operating in a saturated mode, which tends to shrink the bandwidth. The output signal, y (t), is proportional to the amplitudes of the input signals and to their phase difference. 6.
