TL;DR: In this paper, a method is presented that uses the selectivity and the time-discrete character of relaxation oscillators to solve the problem of large crosstalk in electro-mechanical resonators.
Abstract: In many applications, electro-mechanical resonators, such as crystals or micro-machined resonating structures, are used as a frequency-selective element in oscillators. These mechanical resonators often have many resonance modes and suffer from large crosstalk. The reliable selection of the desired resonance mode, at the same time coping with the large crosstalk is often a problem in integrated circuits, especially when the spacing between resonance modes is only small. In this paper, a method is presented that uses the selectivity and the time-discrete character of relaxation oscillators to solve both problems.

TL;DR: In this article, a raktance-to-frequency converter consisting of a Wheatstone bridge and a Comparator is described, whose frequency changes linearly with a resistance change detected by the bridge.
Abstract: A raktance-to-frequency converter consisting of a Wheatstone bridge jfbbved by an integrator and a Comparator is described. It is basically a relaxation oscillator whose frequency changes linearly with a resistance change detected by the bridge. Analyses show that a resolution highear than 0.05% is possible with the simple coilfiguration and an excellent linearity is kept over the wide resistance change by a simple compensatioii method. fit. converter is therefore best suited for un interface oj a resistive sensoK Experimental results are also given to demonstrate its performance

TL;DR: In this paper, a coarse tuning circuit is serially connected between the resonant circuit and the input to the amplifier to minimize noise at the frequency of operation while optimizing the coarse tuning range.
Abstract: A low noise two port voltage controlled oscillator having a coarse tuning circuit serially connected to an inductor to form a resonant circuit. A fine tuning circuit is serially connected between the resonant circuit and the input to the amplifier. A large capacitance series silicon varactor minimizes noise at the frequency of operation while optimizing the coarse tuning range.
