Abstract
Devices and methods include generating biases for input buffers of a semiconductor device. In some embodiments, the semiconductor device includes an input buffer that buffer datas and biasing generation and distribution circuitry that generates and distributes a bias current to the input buffer based at least in part on a reference voltage. The biasing generation and distribution circuitry includes dynamic voltage bias circuitry that adjusts the bias current and reference voltage tracking circuitry that controls operation of the dynamic voltage bias circuitry based on the reference voltage.
