Title: Nianxiong Tan: Innovator in Energy Metering Systems and DSL Applications
Introduction
Nianxiong Tan is a prominent inventor based in Laguna Niguel, California, known for his significant contributions to energy metering systems and digital subscriber line (DSL) technologies. With a total of 11 patents to his name, Tan has demonstrated a commitment to advancing the field of electrical engineering through innovative solutions.
Latest Patents
Among his latest patents, Tan has developed integration methods for energy metering systems using a Rogowski coil. This invention focuses on devices and methods for accurately realizing integration functions, particularly for energy metering systems. The exemplary embodiments of this invention may be constructed as two stable filters for the current and voltage channels. In the analog realization form, the voltage channel's transfer function is designed as a high-pass filter function with at least one zero at the origin. Conversely, the current channel's transfer function is a multiplication of the voltage channel's high-pass filter function and the ideal analog integration function. In the digital realization form, the voltage channel's filter transfer function is also a high-pass filter function, with zeros aligned with the poles of the digital integration function.
Another notable patent is the wide-band analog front-end for DSL applications. This invention encompasses an analog front-end circuit and method that supports multiple DSL standards, including asymmetric digital subscriber line (ADSL) and very-high speed digital subscriber line (VDSL). The circuit integrates multiple circuit blocks that can be selectively included in the transmit and receive paths of a DSL signal. It also allows for selectable gain settings for signal amplifiers and frequency bandwidth for signal filters in both paths. The receive path features an analog-to-digital converter (ADC) that operates at or exceeds the Nyquist sampling rate.
