Multi-bias voltage-controlled oscillator with radiation-resistant function

Abstract

The invention discloses a multi-bias voltage-controlled oscillator with a radiation-resistant function. The multi-bias voltage-controlled oscillator comprises a plurality of bias circuits and a plurality of time delay units; each bias circuit is correspondingly connected with a time delay unit; the time delay units are in ring connection to form an annular oscillator; and each bias circuit receives an input control voltage, generates a bias voltage and then provides the bias voltage for the corresponding time delay unit. The multi-bias voltage-controlled oscillator has the advantages of beingsimple in structure, low in cost, resistant to radiation, low in soft error rate and the like.

Description

technical field [0001] The invention relates to the technical field of voltage-controlled oscillators, in particular to a multi-bias voltage-controlled oscillator with anti-irradiation function. Background technique [0002] In order to meet the demand for integrated circuits with higher integration, more functions and lower power consumption, the feature size and operating voltage of integrated circuits have been continuously reduced, resulting in a sharp increase in the radiation sensitivity of circuits. Voltage-controlled oscillator VCO is an important part of integrated circuits. In the prior art, voltage-controlled oscillators usually do not have the anti-irradiation function. Once the radiation is affected, the output of the frequency divider will be affected by the single-event effect. Mistakes can seriously affect the performance of the circuit. Therefore, there is an urgent need to provide a voltage-controlled oscillator with an anti-irradiation function, so as to ...
