Latest Patents
Griffiths's latest patent, titled "Active Bias Network Circuit for Radio Frequency Amplifier," presents a novel bias network specifically designed for radio frequency signal power amplifiers. The invention incorporates a current source connected to a band gap voltage, producing a current that is proportional to the voltage. Additionally, a reference voltage circuit receives this current, generating a voltage that corresponds not only to the current but also to variations in temperature. An operational amplifier plays a crucial role in decoupling the reference voltage from the power amplifier, enhancing the circuit's stability and reliability. Furthermore, the design includes a power amplifier breakdown protection circuit that diverts avalanche currents away from the power amplifier during mismatching situations. This innovative approach significantly minimizes baseband signal transmission from the power amplifier to the bias network, effectively reducing spurious radiation components.
