To increase the signal to noise ratio, helical resonator is generally employed in between trap signal pick up electrode and Low noise amplifier having high input impedance. Based on available literature and simulation study, a 20MHz Helical resonator was designed and fabricated. The measured resonant frequencyand quality factor of the fabricated resonator is 19.67 MHz and 1030 respectively. Simulation results are found in good agreement with the fabricated resonator parameter. Effect of material’s conductivity on the quality factor of the resonator is also studied.
