A 340 GHz Triple-Push Oscillator With Differential Output in 40 nm CMOS

A low-power triple-push oscillator with differential output is proposed in this letter. By extracting signals from the same current loop, the oscillator can naturally provide differential output without any additional active circuit or passive balun required. Therefore, the output power can be incre...

Description
Summary:A low-power triple-push oscillator with differential output is proposed in this letter. By extracting signals from the same current loop, the oscillator can naturally provide differential output without any additional active circuit or passive balun required. Therefore, the output power can be increased and the chip area and power consumption can be reduced. Realized in 40 nm CMOS technology, the proposed oscillator can oscillate at 340.6 GHz while providing equivalent isotropically radiated power (EIRP) as -21.8 dBm. The power consumption is only 34.1 mW from a 0.9 V supply. The oscillator core only occupies area of 0.028 mm 2 .
