Abstract
A signal generator is configured to generate a signal with an amplitude sweep, the signal generator having circuitry comprising: a set of control components, each control component of the set being arranged to be switchably activated in parallel in the circuitry such that an amplitude of the signal has an intrinsic dependence on the number of the control components activated; a shift register controllable by a clock line and comprising a number of bits, each bit of the number of bits controlling activation of a respective control component of the set of control components such that the control components are arranged to be activated or de-activated in a pre-determined order by shifting activation or de-activation bits into the shift register, wherein the shifting is paced by the clock line; and a clock signal generator configured to output a clock signal with a time modulation on the clock line.
