This thesis presents two millimeter-wave high-division-ratio injection-locked frequency divider designs, including a K-band divide-by-3 injection-locked frequency divider (ILFD) and a multi-modulus current-reused injection-locked frequency divider. Frequency divider is one of the most important parts of phase-locked loop (PLL). And the frequency divider can be applied in radar and wireless communication systems. Both of the circuit, in this thesis, are designed and implemented in TSMC 90-nm CMOS process.
The first circuit is that a K-band divide-by-3 injection-locked frequency divider integrating with pre-amplifiers. We adopt the topology of the divide-by-3 ILFD with an injection-switched cross-coupled pair (IS-CPP) technique and a cascode common source (CS) amplifer as our designed circuit. Such a design is convenient to integrate the divider into the PLL. Because of the pre-amplifier, the input sensitivity of the divider is enhanced. The free-running frequency of the designed divider is at 8.01 GHz. When the input power of the injection signal is -10 dBm, the measured locking range is 4.9 GHz (between 20.5 GHz and 25.4 GHz). When the input power of the injection signal is -40 dBm, the measured locking range is still kept with 0.4 GHz (between 23.9 GHz and 24.3 GHz). The power consumptions of the amplifier and the ILFD are 2.37 mW and 1.7 mW, respectively.
The second design is that a multi-modulus current-reused injection-locked frequency divider (ILFD). This divider has five division-ratio modes (with the division ratios of 2, 4, 6, 8 and 10). The free-runing frequency at the maximum and minimum values are 3.656 GHz and 4.19 GHz, respectively, when the switching capacitance. The lowest and highest operation frequency of this divider is 2.7 GHz and 41.2 GHz, respectively. And the divide-by-6 mode has the widest locking range of the divider, the locking range is 15.1 GHz between 11.9 GHz and 27 GHz. The power consumption is 6.12 mW at 0.9 V supply voltage. And the range of the operation frequency bands is quite wide. Therefore, it can be applied to the integration of the radar or 4G, 5G wireless communication systems.
