%X This study presents a push-push oscillator architecture based on differential gate equalisation to enhance theoscillation frequency while providing relatively high output power with ultra-compact layout form factor. The frequencyenhancement is derived as a function of the equivalent RLC model of the oscillator's main constituents. The proposed principleis applied to a terahertz oscillator in the 200-300 GHz range to mitigate the excessive substrate and skin effect losses instandard digital 65-nm complementary metal-oxide-semiconductor technology at such high frequencies. The design concept isvalidated using two single-stage push-push oscillators. The first oscillator shows -8.1 dBm output power at 250 GHz oscillationfrequency and -106.8 dBc/Hz phase noise at 10 MHz offset while consuming 76 mW power from 1.5 V DC supply voltage. Thechip area is 200 × 250 μm<sup>2</sup>. The second oscillator provides -14.8 dBm output power at 285 GHz and -106 dBc/Hz phase noiseat 10 MHz offset with 80 mW power consumption from 1.5 V DC supply. The chip area is 200 × 200 μm<sup>2<sup>.
