  • Abstract
    A new RC-amplifier resonator has a pole Q which is invariant under passive element drift. The differential sensitivities SxQare all zero. The macroscopic sensitivities give ΔQ/Q=-12 ppm for ΔZ/Z=1 percent. Thermal coefficients of R and C can thus be chosen for constant center frequency in several ways without affecting the Q stability.
