Latest Patents

One of Glasbrener's latest patents is titled "Active linearization for broadband amplifiers." This invention focuses on converting a data signal voltage at a signal input node into an output signal current at a signal output node. The design incorporates a first transistor device that contributes to the output signal current while managing larger signal swings through reduced transconductance. A second transistor enhances the effective resistance of a gain degeneration resistor associated with the first transistor, thereby maintaining or improving the overall gain between the input and output nodes. The patent also describes various configurations, including multiple secondary stages and negative feedback mechanisms to reduce component variability.

Another significant patent by Glasbrener is "Non-linear transistor circuits with thermal stability." This invention employs separate signal biasing and DC biasing to enhance power efficiency and prevent thermal runaway. The improved amplifier utilizes a DC bias voltage supply, allowing for a large resistance value in the DC bias network to prevent thermal issues while maintaining a small resistance for the signal biasing network to boost efficiency. The design achieves thermal equilibrium by managing the voltage drop across the DC bias resistance, which stabilizes the transistor's operating conditions.
