  • AMPLIFIER WITH BIAS CIRCUIT HAVING REPLICATED TRANSCONDUCTANCE DEVICES
    Publication number: 20240022221
    Abstract: Devices and techniques for amplifying a signal are disclosed. For instance, an amplifier includes an input node and an output node; a first gain segment including: a first transistor, where a gate of the first transistor is coupled to the input node, a first terminal of the first transistor is coupled to a ground, and a second terminal of the first transistor is coupled to the output node; a second gain segment including: a second transistor, where a gate of the second transistor is coupled to the input node, a first terminal of the second transistor is coupled to the ground, and a second terminal of the second transistor is coupled to the output node, where the first gain segment and the second gain segment are arranged in parallel with respect to the output node; and a bias circuit.

  • GPS RF front end IC with programmable frequency synthesizer for use in wireless phones
    Patent number: 7512385
    Abstract: A GPS RF Front End IC containing a Programmable Frequency Synthesizer is disclosed. The GPS RF front end IC having a programmable frequency synthesizer allows a relatively fixed internal frequency plan while able to use a number of different reference frequencies provided by the host platform, which can be a wireless phone, or other such device, which can provide an accurate reference frequency signal.

  • Fractional-R frequency synthesizer
    Patent number: 7388939
    Abstract: A fractional-R synthesizer having a divider with rational increments and configurable in rational steps able to generate a plurality of frequencies in rational increments from a reference frequency. A voltage-controlled oscillator frequency (fVCO) is related to the reference frequency (fREF) by: fREF=fVCO/RAVG, where RAVG is the average value of the rational divide value “R” over a large number of reference cycles.
