Abstract
This work proposes a D-band 5th sub-harmonic injection-locked oscillator (SILO) implemented in a 22nm fully-depleted silicon-on-insulator (FDSOI) CMOS technology. The circuit utilizes a serial injection technique, including p-MOS diodes, to enhance the non-linear transconductance and increase the generation of sub-harmonic currents and, thus, enlarging the lock range. Compact self-biased inverter input buffers are employed to provide signal amplification and steep harmonic-rich square voltage waveforms. The SILO achieves a 4GHz lock range at nominal bias, extendable by back-gate biasing to an overall lock range of 6.8 GHz from 145.6 to 152.4 GHz. The output power reaches -5.7dBm while consuming only 31mW and occupying a compact core area of 200 × 95μm.
