Title: The Innovative Contributions of Mark K Lesher

Introduction

Mark K Lesher is a notable inventor based in Mohrsville, PA (US). He has made significant contributions to the field of electrical engineering, holding a total of 3 patents. His work primarily focuses on advanced electrical circuits and integrated systems.

Latest Patents

One of his latest patents is a "Tunable filter with bypass." This invention features an electrical circuit that includes a filter bypass mode. The circuit comprises an amplifier with an inverting terminal, a noninverting terminal, and an output terminal. It also includes at least one first capacitor coupled to the inverting terminal of the amplifier through at least one first switch, and at least one second capacitor coupled to the noninverting terminal of the amplifier through at least one second switch. This electrical circuit provides filtering when the first and second switches are in a first state, and when the switches are in a second state, it provides substantially no filtering.

Another significant patent is the "On-chip trim link sensing and latching circuit for fuse links." This integrated circuit includes a pulse generator that generates a pulse of a predetermined duration. A first switch, controlled by the pulse, drives current into a fuse link when the pulse takes on a first logic level. The first switch prevents the flow of current into the fuse link when the pulse takes on a second logic level. A latch is coupled to the fuse link to sense a logic level developed during the pulse. The latch may be cleared by the leading edge of the pulse, and the logic level developed at the fuse link due to the driven current is latched into the latch by the trailing edge of the pulse, indicating whether the fuse link was blown or not.
