Title: Jaakko Haapalahti: Inventor in Node Voltage Control

Introduction

Jaakko Haapalahti is an inventor based in Oulu, Finland. His listed patent concerns a circuit technique for controlling and maintaining voltage at a node. He is associated with Nordic Semiconductor ASA.

Latest Patents

Haapalahti’s listed invention, “Node voltage control,” describes a circuit with an analog voltage supply module, a clock, and a clocked digital control module. The circuit applies a bias voltage to supply a node, samples the node’s voltage at a clock edge, and stores the sampled value. It then disables the bias voltage and supplies the stored voltage to the node. When a refresh criterion is met, the digital control module initiates a refresh sequence that reapplies the bias voltage, samples the node again at a clock edge, and stores the refreshed value. Haapalahti is credited with 1 patent.

Career Highlights

Haapalahti’s patent work addresses voltage control in electronic circuitry, including a method for refreshing a stored node voltage. His professional association with Nordic Semiconductor ASA connects his work to a company focused on semiconductor technology.
