“…As observing the measured phase noise, the noise degradations of the ÷2, ÷3, and ÷4 modes are close to the theoretical values of 6, 9.5, and 12 dB estimated for the frequency division by 2, 3, and 4 [17]. The performance comparisons with published multi-modulus FDs are summarized in Table 1 [6][7][8][9][10]. The proposed divider uses the switches to select the triple division modes and retains the characteristic of the RFD with a high-speed operation and wide locking range.…”

Abstract-A high-speed triple-modulus frequency divider (FD) is designed and fabricated in a 90-nm CMOS process. With three pairs of nMOS switches inserted in the signal paths of the regenerative divider, the FD can offer three selectable division ratios of 1/2, 1/3, and 1/4. The corresponding behavior model of the proposed divider is utilized to explain the operation principle and analyze the locking range. From the experimental results, the divider consumes 6.8 mW of dc power from a 1.2-V supply voltage, and the locking ranges for the 1/2, 1/3, and 1/4 divide modes are 16-23.8, 12.3-18, and 16.8-22.8 GHz, respectively. The maximum input frequencies of 23.8, 18, and 22.8 GHz for the 1/2, 1/3, and 1/4 division modes are demonstrated that the divider is attractive for application to a frequency synthesizer.

Abstract-In this work, the linearity of a high gain Harmonic Self Oscillating Mixer (HSOM) is analyzed. In order to obtain high conversion gain, the working point of the HSOM is established close to a Hopf bifurcation point. The traditional figures of merit used to characterize the linearity of conventional mixers cannot be directly applied to characterize the behavior of autonomous circuits, because of the influence of the input RF signal power on the autonomous signal parameters. The 1 dB compression point and the third order distortion will be analyzed as a function of the harmonic content and maximum gain of the circuit. From the collected data, the optimum harmonic content and the maximum conversion gain of the HSOM can be selected, for a particular application, in order to minimize the output IF signal distortion.

Abstract-In this work, an electronically tunable large range phase shifter based on a broadband Injection-Locked Third Harmonic SelfOscillating Mixer (IL3HSOM) is designed and analyzed. This multifunctional circuit generates a down-converted Intermediate Frequency (IF) signal and provides a theoretical 540 • continuous phase shift range. The conversion gain and the bandwidth of the circuit are optimized through bifurcation control techniques. The IL3HSOM will be used as the core of a broadband phased antenna array with electronic beam-steering capabilities. The use of a multi-harmonic load based on an arbitrarily width modulated transmission line allows the nonlinear optimization of the circuit phase shift frequency response to compensate the frequency scanning effect, which negatively influences the performance of broadband antenna arrays.
