Abstract
Disclosed herein is a temperature compensated crystal oscillator, TCXO, comprising: a crystal oscillator arrangement configured to generate an output signal of the temperature compensated crystal oscillator; and a temperature sensor arranged to generate a temperature sensor signal, wherein the output signal of the crystal oscillator arrangement is controlled in dependence on the temperature sensor signal; wherein: the temperature sensor comprises a plurality of transistor circuits; each transistor circuit comprises a transistor and a bias circuit; each transistor circuit is arranged to output a temperature signal that is dependent on the temperature of the transistor comprised by the transistor circuit; each bias circuit is configured such that the noise level in each output temperature signal is low; and the plurality of transistor circuits are arranged so that the temperature sensor signal is dependent on each of the plurality of output temperature signals.
