Latest Patents
Two of Braathen's latest patents exemplify his forward-thinking approach to amplifier technology:
1. **Linearized Output Control of a Nonlinear Amplifier**: This invention details an amplifier circuit designed to deliver precise linear control over the output of a nonlinear amplifier. It includes a nonlinear gain controllable amplifier and an output control circuit that samples the signal output from the amplifier. This circuit alternately transmits the sampled output and a baseband signal to a detector, which produces a signal representative of the power level. The resulting signals are stored in sample-and-hold circuits, allowing a difference amplifier to fine-tune the amplification in order to linearly track the baseband signal.
2. **Active Filtering Mixer**: This innovative design incorporates a feedback arrangement that dynamically cancels unwanted components in the mixer's output by feeding them back out of phase. This method not only minimizes the negative impact of these components on downstream devices but also stabilizes the mixer's DC operating point, aiding in the maintenance of maximum dynamic range. Moreover, it allows for linearization of the in-band output while enhancing the overall performance of the mixer across its operational spectrum.
