With a total of 3 patents to his name, Niederl's work showcases his expertise and innovative spirit.
Latest Patents
One of his latest patents is the "High Q linear controlled variable capacitor using translinear amplifier." This invention involves a voltage-controlled variable capacitor that consists of multiple fixed capacitor segments and corresponding switching elements. The use of translinear amplifiers allows for precise control of each switching element, achieving a nearly linear change in capacitance with minimal overlap during switching. This design results in a high Q-factor due to the low RDSon and high RDSoff characteristics of the fully switched stages. Additionally, it eliminates the temperature and voltage dependencies found in other solutions, such as varactor diodes.
Another significant patent is the "High Q linear controlled variable capacitor." Similar to his previous invention, this patent focuses on a voltage-controlled variable capacitor that linearly switches each element in sequence. The techniques disclosed ensure that only a minimal number of switching stages are active at any given time, further enhancing the linearity of capacitance change in relation to tuning voltage.
