Digital power amplifier with I/Q combination

3D Imager and Method for 3D imaging

3D imager comprising at least one pixel, each pixel comprising a photodetectorfor detecting photon incidence and a time-to-digital converter system configured for referencing said photon incidence to a reference clock, and further comprising a reference clock generator provided for generating the reference clock, wherein the reference clock...

High resolution millimeter wave digitally controlled oscillator with reconfigurable distributed metal capacitor passive resonators

A novel and useful millimeter-wave digitally controlled oscillator (DCO) that achieve a tuning range greater than 10% and fine frequency resolution less than 1 MHz. Switched metal capacitors are distributed across a passive resonator for tuning the oscillation frequency. To obtain sub-MHz frequency resolution, tuning step attenuation techniques...

Wideband FM demodulation by injection-locked division of frequency deviation

A novel and useful wideband FM demodulator operating across an 8 GHz IF bandwidth for application in low-power, wideband heterodyne receivers. The demodulator includes an n-stage ring oscillator that is injection locked to a wideband input signal. Locking to the input frequency, it divides the FM deviation by n, thereby facilitating as well as...
