  • Method and apparatus for modulating digital data
    Patent number: 6560296
    Abstract: The modulator includes an oscillator generating signals, each having a different phase, and a selector receiving digital data. When the digital data received by the selector changes logic state, the selector supplies a first and second plurality of signals generated by the oscillator to first and second non-linear amplifiers, respectively. An adder then adds the output of each amplifier to generate a radio frequency output.

  • 2.5V, 30-100 MHz 7th order equiripple delay continuous-time filter and variable gain amplifier
    Patent number: 6268765
    Abstract: A circuit is designed with a first transconductor circuit (903) with a first input terminal (901) coupled to receive a voltage signal, a second input terminal (1017) coupled to receive a control signal and an output terminal. The first transconductor circuit has a gain responsive to the control signal. A first integrator circuit (905) has an input terminal coupled to the first transconductor circuit output terminal and has an output terminal. A second transconductor circuit (909) has an input terminal coupled to the first integrator circuit output terminal and an output terminal. A second integrator circuit (911) has an input terminal coupled to the second transconductor circuit output terminal and has an output terminal.
