Abstract: Broadband analog radio-frequency devices can be used to create building blocks for scalable analog signal processors that operate over bandwidths of 50 MHz to 20 GHz or more. Example devices include integrators (transconductors), digitally controlled attenuators, buffers, and scalable summers implemented using deep sub-micron CMOS technology. Because the devices are implemented in CMOS, the ratio of trace/component size to signal wavelength is about the same as that of low-frequency devices implemented in printed circuit boards. Combining this scaling with high gain/high bandwidth enables implementation of feedback and programmability for broadband analog signal processing.

Abstract: Provided is a method and system for producing a drive signal for a current steering amplifier. An exemplary method comprises receiving a supply voltage signal and a differential input signal as a circuit input. A differential amplifier drive signal is produced in response to the received supply voltage signal, the received differential input signal, and the received differential control signal. The received differential input signal is adjusted to a value where magnitudes of negative and positive components of the differential control signal become equal to one another and are within a predetermined amount of a magnitude of the supply voltage signal.
