Latest Patents
One of Ward's latest patents is for a fully integrated tuner architecture. This invention describes an integrated receiver with channel selection and image rejection that is substantially implemented on a single CMOS integrated circuit. The receiver front end provides programmable attenuation and a programmable gain low noise amplifier. The frequency conversion circuitry utilizes LC filters integrated onto the substrate in conjunction with image reject mixers to achieve sufficient image frequency rejection. Filter tuning and inductor Q compensation over temperature are performed on-chip. The filters employ multi-track spiral inductors and are tuned using local oscillators to adjust a substitute filter. Frequency scaling is applied to match the component values of the filter being tuned. Additionally, frequency planning provides extra image rejection. The local oscillator signal generation methods on-chip include PLL out-of-band local oscillation and direct synthesis for in-band local oscillators. The VCOs in the PLLs are centered using a control circuit to optimize the tuning capacitance range. A differential crystal oscillator serves as a frequency reference, and differential signal transmission is utilized throughout the receiver.
