Abstract: PURPOSE: A phase locked loop (PLL) suitable for a spin transfer torque oscillator is provided to improve the phase noise property of the oscillator advantageous to high speed communication. CONSTITUTION: A phase locked loop (PLL) suitable for a spin transfer torque oscillator includes an oscillating part (1) and a frequency locking part (2). The oscillating part has the oscillators (11,12) of which the oscillating frequencies are inversely proportional to an input current. The oscillators are arranged into n x m matrices in the oscillating part. Two oscillators are mutually integrated into a pair of the oscillators in a row, and then are finally pre-scaled into one output in a column direction. The frequency locking part outputs the first row of the oscillating part into an operating frequency, and compares the output frequency of the last row with a referential frequency in order to lock the operating frequency.

Abstract: PURPOSE: A phase shifter is provided to implement small insertion loss through a phase delay of a signal by controlling an effect dielectric constant of a substrate with an air gap. CONSTITUTION: A GCPW(Ground Co-Planar Wave Guide) phase shifter is composed of a transfer substrate(100), a first metal layer(102), a signal line(104), a second metal layer(106), and an air gap(108). The transfer substrate is formed by using a plurality of ceramic substrates. The first metal layer is grounded in a lower part of the transfer substrate. A signal line is formed in the constant area of the upper part of the transfer substrate. The second metal layer is grounded in an upper part of the transfer substrate. The air gap is formed inside the transfer substrate between the first metal layer and the signal line.
