Latest Patents

One of his latest patents is a "Flexible monolithic continuous-time analog low-pass filter with minimal circuitry." This invention discloses a completely tunable second-order low-pass filter that requires minimal active circuitry. The filter allows for a flexible choice of parameters such as cutoff frequency, DC gain, and Q factor by selecting appropriate resistor values for a single integrated circuit. This design utilizes much lower capacitance and active circuitry compared to other standard low-pass circuit configurations.

Another notable patent is the "Operational filter building block." This invention presents a 3-terminal operational filter circuit that can be configured to construct various types of active filters. The circuit can provide 2nd order low pass and band-pass frequency responses by coupling three resistors to the filter terminals. Additionally, it can be configured for 2nd order band-pass and high pass frequency responses by using two resistors and a capacitor. The filter circuit can be cascaded to create higher order filters, and users can select specific values for the circuit elements to achieve desired performance characteristics.
