Abstract
A hadamard gate includes two strongly cross-coupled limit cycle oscillators. Each limit cycle oscillator includes an amplifier, a summing node, an integrator, a hysteresis quantizer, a self-feedback 1-bit DAC (Digital-to-Analog Converter) and a cross-feedback 1 bit DAC. Each oscillator output drives its own self-feedback DAC and the cross-feedback DAC of the other oscillator.
