Abstract: A high-speed current-mode clock driver includes feedback circuitry to maintain the voltage swing of a biasing node within a defined range. The current-mode clock driver includes a PMOS and an NMOS transistor receiving an oscillating signal at their gate terminals. The drain terminals of the PMOS and NMOS transistors are respectively coupled to input terminals of first and second variable conductivity circuits whose output terminals are coupled to a common node. A control circuit increases the conductivities of the first and second variable conductivity circuits in response to decreases in voltage swing of the common node, and decreases the conductivities of the first and second variable conductivity circuits in response to increases in voltage swing of the common node. The first and second variable conductivity circuits are optionally PMOS and NMOS transistors respectively.
