Introduction

Thomas K Johnston is a notable inventor based in Austin, TX, with a remarkable portfolio of 8 patents. His work primarily focuses on advancements in adjustable buffer technology, which plays a crucial role in electronic circuits.

Latest Patents

Among his latest innovations is the "Clock Tree Adjustable Buffer." This invention features an adjustable buffer that includes a series of P-channel devices with current paths connected between a first voltage supply and at least one output node. Additionally, it incorporates a series of N-channel devices that have current paths linked between the output node and a second voltage supply. The control electrodes of these devices are connected to either an input node or a corresponding voltage supply, forming sets of selectable connections that adjust the delay from the input node to the output node. This technology can be defined in an integrated circuit mask or implemented using electronic switches. The P- and N-channel devices can be configured in either a balanced or imbalanced manner, allowing for both inverting and non-inverting buffer configurations.

Another significant patent is also titled "Clock Tree Adjustable Buffer," which describes a system that includes a first series of P-channel devices and a first series of N-channel devices. These devices are arranged to adjust the delay from the input node to the first output node. This clock distribution system features multiple uniform adjustable buffers that connect at least one root node to various destination nodes, with each buffer adjustable between minimum and maximum delays.
