| 摘要: |
| 为提高辐照环境下振荡器工作的可靠性，提出一种交织结构的抗辐照设计加固压控振荡器（Voltage-Controlled Oscillator，VCO），该VCO由采用交织结构的延时单元构成，该延时单元支持多数表决功能，可以抑制单粒子瞬变的影响；该VCO环路中无须引入额外的专用表决模块，可以产生均匀的多相位输出。所提出的加固差分VCO是基于130 nm体硅互补金属氧化物半导体工艺设计的。模拟结果表明，所设计的加固VCO在100 fC~800 fC沉积电荷量的轰击范围内，其所产生的最大相位偏移不超过0.35 rad。 |

| Abstract: |
| In order to improve the operation reliability of oscillator, a novel radiation-hardened-by-design VCO (voltage-controlled-oscillator) using interleaved structure was presented. The VCO consists of multi-stage delay cells which apply interleaved structure and can complete majority decision voter, so it is tolerant to single-event transient effect. Additionally, the VCO can generate symmetric multi-phase output as no additional module for majority decision voter is needed to be introduced in it. The radiation-harden differential VCO was implemented in a 130 nm bulk complementary metal oxide semiconductor process. Simulation results show that, when deposited charges range from 100 fC to 800 fC, the maximum phase displacement generated by a single simulated ion strike for the proposed VCO output is less than 0.35 rad. |
