Abstract
An oscillator circuit () is disclosed. It comprises N amplifier circuits (A-A), connected in a ring and has a first and a second supply terminal (s, s). Each amplifier circuit (A-A) comprises an input transistor (M) having its gate connected to the input (in) of the amplifier circuit, its drain connected to an internal node (x) of the amplifier circuit, and its source connected to the first supply terminal (si). Furthermore, each amplifier circuit (A-A) comprises a first resonance circuit (R) comprising a first inductor (L) and a first capacitor (C), wherein the first inductor (L) is connected between the internal node (x) and the output (out) of the amplifier circuit, and the first capacitor (C) is connected between the output (out) of the amplifier circuit and one of the first and the second supply terminals (s, s). Moreover, each amplifier circuit (A-A) comprises a second resonance circuit (R) comprising a second inductor (L) and a second capacitor (C), wherein the second inductor (L) and the second capacitor (C) are connected in parallel between the internal node (x) and the second supply terminal (s).
