Abstract: Methods and systems are provided for generating an oscillating signal for use as a clock in digital logic timing. The oscillating signal is generated via a differential RC relaxation oscillator including an oscillator core and biasing circuitry. The oscillator core may be configured such that the oscillating signal it generates is substantially sinusoidal or pseudo-sinusoidal and contains less harmonic content relative to a square wave signal. The biasing circuitry may be configured to have a reduced dependence on temperature so that the biasing values it provides vary less with temperature.

Abstract: Aspects and examples described herein provide a variable gain amplifier circuit and assembly. In one example, a variable gain amplifier circuit includes a signal input, a signal output, and a variable gain amplifier including a plurality of unit cell groups coupled between the signal input and the signal output, the variable gain amplifier configured to provide an adjustable gain to a signal received at the signal input during each of a plurality of amplify modes of the variable gain amplifier, each of the plurality of amplify modes corresponding to at least one unit cell group of the plurality of unit cell groups. A bypass path including a fixed attenuator is coupled in parallel with the variable gain amplifier between the signal input and the signal output to selectively couple the signal input to the signal output through the fixed attenuator during a bypass mode.

Abstract: Amplifier systems and methods are provided that include a fixed gain amplification stage coupled to an adjustable attenuation stage further coupled to a variable gain amplification stage. A controller controls an amount of attenuation provided by the adjustable attenuation stage and an amount of gain provided by the variable gain amplification stage to maintain any of various noise, efficiency, and/or linearity requirements of the amplifier system.
