Abstract
The present invention provides an oscillator circuit and associated oscillator device. The oscillator circuit comprises a negative-temperature-coefficient (NTC) bias current generating circuit and a set of oscillator sub-block circuits. The NTC bias current generating circuit is coupled between a supply voltage and a ground voltage, and is arranged to generate at least one NTC bias current. The set of oscillator sub-block circuits are coupled to each other to form an oscillator. Each oscillator sub-block circuit of the set of oscillator sub-block circuits comprises a plurality of transistors coupled between the supply voltage and a node within the NTC bias current generating circuit, wherein the NTC bias current generating circuit and the aforementioned each oscillator sub-block circuit share at least one transistor in the plurality of transistors.
