Continuously tuning a transconductance. Coupling a degeneration resistance from a first source of a first transistor in a differential pair of transistors to a second source of a second transistor in the differential pair of transistors. Applying a second variable degeneration resistance in parallel to the first degeneration resistance in response to the application of a first variable control voltage. And applying a third variable degeneration resistance in parallel to the first degeneration resistance and the second degeneration resistance in response to the application of a second variable control voltage having a fixed voltage offset from the first variable control voltage.

A specialty eyewear device including an optical frame that carries a pair of highly reflective surfaces that permit a wearer to experience an angular offset between the direct line of vision and the effective line of vision. No refraction occurs in the performance of the device, and no image reversal takes place. Modifications of the invention allow for certain angular adjustments in the device which can both change the actual angular offset which occurs between direct and effective line of vision, and permits angular rotation of a given angular offset.

An improved differential amplifier having circuitry to enhance the slew rate and to provide a means for nulling the offset voltage during fabrication of the amplifier as an integrated circuit. The differential amplifier comprises an input stage connected to a current mirror. A slew rate enhancement circuit injects current into selected points of the circuit when the input voltage exceeds a predetermined threshold. An offset trim circuit injects a selected amount of current into the current mirror to alter the current flow between the input stage and the current mirror, thereby reducing the offset voltage. The selected amount of current is dictated by diodes which may be permanently shorted at various stages during fabrication, both before and after the amplifier is enclosed in an IC package.

An integrated communications system. A substrate having a receiver disposed on the substrate for converting a received signal to an IF signal, a digital IF demodulator disposed on the substrate and coupled to the receiver for converting the IF signal to a demodulated baseband signal, and a transmitter disposed on the substrate operating in cooperation with the receiver to establish a two way communications path.
