Abstract
An oscillator () comprises a tank circuit (), a first transistor (M) and a second transistor (M), and the second transistor (M) occupies an area of silicon that is smaller than an area of silicon occupied by the first transistor (M). A switching apparatus (Sw. . . Sw) selects either one of a first oscillator topology and a second oscillator topology, where in the first oscillator topology, the tank circuit () is coupled to the first transistor (M) in a first feedback configuration to provide feedback around the first transistor (M), and in the second oscillator topology, the tank circuit () is coupled to the second transistor (M) in a second feedback configuration that is different to the first feedback configuration to provide feedback around the second transistor (M).
