Title: Innovations of L Rolando Ortega-Pohlenz
Introduction
L Rolando Ortega-Pohlenz is a notable inventor based in Austin, TX (US). He has made significant contributions to the field of digital source-measure units (SMUs). With a total of 4 patents, his work focuses on enhancing the performance and functionality of electronic measurement systems.
Latest Patents
One of his latest patents is titled "Compensation methods for digital source-measure-units (SMUs)." This invention involves implementing digital control loops for output voltage and output current in SMUs. The output voltage and current are measured using dedicated analog-to-digital converters (ADCs). The readings from the ADCs are compared to a setpoint established in a digital loop controller. The controller produces an output to drive a digital-to-analog converter (DAC) until the desired levels are achieved. Additionally, the digital loop controller incorporates integrating functions and a compensation function featuring pole-zero pairs to stabilize the outputs. The coefficients for the compensation function are calculated based on user-programmable parameters.
Another significant patent is "Fast current saturation recovery for a digital source measure unit (SMU)." This invention also utilizes digital control loops for output voltage and current. The system measures the output using dedicated ADCs and compares the readings to a setpoint in a digital loop controller. The controller performs a threshold check to ensure the output current remains within a specified measurable range. If the current exceeds this range, an override signal is generated to quickly return it to the measurable range. Once stabilized, the DAC is driven according to the digital control loops for both output voltage and current.
