In this paper, a distributed biasing technique is proposed to improve the single event transient (SET) tolerance in LC-tank voltage controlled oscillators. The charge generated by a radiation strike at the drain of the bias current transistor results in voltage change at the drain node, which causes change in the output impedance of the transistor. This effect is more pronounced in the case of distributed...
We present a wide tuning range quadrature phase LC oscillator in this paper. A combination of series-coupled and parallel-coupled topologies between the two LC tanks in the oscillator is used. Series-coupled topology ensures that a desired phase sequence is achieved, whereas, tunability and switching of parallel-coupling helps in achieving very wide tuning range. Furthermore, use of varactors, which...
CMOS integrated circuits are prone to hazards such as Single Event Transients (SETs) caused by radiation strikes in high energy radiation environments. For synthesis of high frequency signals for circuits used in such environments, we propose use of quadrature phase LC oscillators. In addition to providing higher tolerance to SETs, these oscillators are also able to provide wider tuning range, which...
