Latest Patents

Wong holds a patent titled "Center frequency control of an integrated phase rotator band-pass filter using VCO coarse trim bits." This invention involves a phase rotator for a Cartesian feedback power amplifier in the final stage of a transmitter. The patent features an integrated voltage-controlled tunable resonant circuit that facilitates band-pass filtering at a center frequency determined by local oscillator (LO) coarse trim control signals. This advanced circuit design effectively attenuates input signal harmonic levels across large fractional bandwidths, enhancing the performance of the downconverter in the feedback LO path without adding an excessive number of poles in the band-pass filter. By utilizing a binary-weighted coarse trim value to control the gain of the LO, the invention sets a bank of voltage-variable capacitors (VVC) within the voltage-controlled tunable resonant circuit, managing the center frequency across two 2-pole band-pass filters, ultimately achieving a composite 4-pole band-pass filter at the input of the poly-phase quadrature generation circuit in the feedback LO path.
