Title: Innovations of Johannes P Verdaasdonk
Introduction
Johannes P Verdaasdonk is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of electronics, particularly in the development of differential amplifiers and voltage-current converters. With a total of five patents to his name, Verdaasdonk's work has had a substantial impact on analog-to-digital conversion technologies.
Latest Patents
Verdaasdonk's latest patents include a differential amplifier with a signal-dependent offset and a voltage-current converter. The differential amplifier features two input transistors and two cross-coupled transistors arranged in a translinear loop. This design allows for a difference voltage across a resistance connected between the emitters of the cross-coupled transistors, which is equal to the difference voltage across the input terminals plus the sum of the offset voltages across resistors in series with the respective emitters of the input transistors. The output signal amplitude produced is larger than the input signal amplitude, making it suitable for use in multi-step dual-residue analog-to-digital converters. The voltage-current converter also employs a similar translinear loop configuration, enabling a larger output signal amplitude while compensating for decreasing current gain at high frequencies.
