摘要： Current-controlled CMOS (C3MOS) fully differential integrated wideband amplifier/equalizer with adjustable gain and frequency response without additional power or loading. A novel approach is presented by which adjustable amplification and equalizer may be achieved using a C3MOS wideband data stage. This may be referred to as a C3MOS wideband data amplifier/equalizer circuit. This employs a wideband differential transistor pair that is fed using two separate transistor current sources. A switchable RC network is communicatively coupled between the sources of the individual transistors of the wideband differential transistor pair. There are a variety of means by which the switchable RC network may be implemented, including using a plurality of components (e.g., capacitors and resistors connected in parallel). In such an embodiment, each component may have an individual switch to govern its connectivity in the switchable RC network thereby allowing a broad range of amplification and equalization to be performed.

摘要： Current-controlled CMOS (C3MOS) wideband input data amplifier for reduced differential and common-mode reflection. Impedance matching and bandwidth extension provides desired gain at higher frequencies and may be achieved at the interface between silicon and package and/or circuit board within various integrated circuits that may be employed within communication devices. In some instances, a differential transistor pair is employed that also includes Miller capacitors coupled between the gate of one transistor of the differential transistor pair to the drain of the other transistor of the differential transistor pair. This can also include series load connected resistors and inductors coupled between the respective drains of the transistors of the differential transistor pair to a power supply voltage. Also, series connected input inductors may also couple to the gates of the transistors of the differential transistor pair.
