Abstract:
There is presented a high bandwidth circuit for high-speed transceivers. The circuit may comprise an amplifier combining capacitor splitting, inductance tree structures, and various bandwidth extension techniques such as shunt peaking, series peaking, and T-coil peaking to support data rates of 45 Gbs/s and above while reducing data jitter. The inductance elements of the inductance tree structures may also comprise high impedance transmission lines, simplifying implementation. Additionally, the readily identifiable metal structures of inductors and t-coils, the equal partitioning of the load capacitors, and the symmetrical inductance tree structures may simplify transceiver implementation for, but not limited to, a clock data recovery circuit.
