Abstract

In this paper, a scalable and reconfigurable architecture is presented for digitally programmable sub-THz waveform generation in CMOS. The architecture allows individual control of both amplitudes and phases of harmonic frequencies beyond fmax to achieve waveform shaping. This is enabled through controlled interference of multiple traveling-waves with rich harmonic components and delays. As an example, inspired from mode-locked laser, picosecond pulse generation is demonstrated in CMOS with a measured pulse-width of 2.6ps and 0.46 mW output power for the pulse train. To the best of the authors' knowledge, this is the smallest pulse width demonstrated in integrated circuit technology with additional capability of dynamic reconfiguration. The chip is fabricated in 65nm LP CMOS process.
