چکیده انگلیسی
This paper demonstrates the integration of giant magnetoresistance (GMR) spin torque oscillators (STO) with dedicated high frequency CMOS circuits. The wire-bonding-based integration approach is employed in this work, since it allows easy implementation, measurement and replacement. A GMR STO is wire-bonded to the dedicated CMOS integrated circuit (IC) mounted on a PCB, forming a (GMR STOÂ +Â CMOS IC) pair. The GMR STO has a lateral size of 70Â nm and more than an octave of tunability in the microwave frequency range. The proposed CMOS IC provides the necessary bias-tee for the GMR STO, as well as electrostatic discharge (ESD) protection and wideband amplification targeting high frequency GMR STO-based applications. It is implemented in a 65Â nm CMOS process, offers a measured gain of 12Â dB, while consuming only 14.3Â mW and taking a total silicon area of 0.329Â mm2. The measurement results show that the (GMR STOÂ +Â CMOS IC) pair has a wide tunability range from 8Â GHz to 16.5Â GHz and improves the output power of the GMR STO by about 10Â dB. This GMR STO-CMOS integration eliminates wave reflections during the signal transmission and therefore exhibits good potential for developing high frequency GMR STO-based applications, which combine the features of CMOS and STO technologies.
