摘要： It is an object to provide a complex negative feedback frequency selection output circuit that can produce an output signal of a high resonance sharpness Q factor and an oscillation circuit using the same. The complex negative feedback frequency selection output circuit according to the present invention, frequency-selectively relays only the residual components of one of a signal in phase with (or a signal opposite in phase to) a feedback processed signal obtained by negative feeding back a feedback signal to an input frequency signal, with a rejected frequency band being left out, while relaying at least a real number component of the other, and comprises a feedback path which relays a difference signal between (or a sum signal of) the selectively relayed output and the relayed output of the real number component, as the feedback signal. The gain of a loop including this feedback path is variable and can be set manually or automatically.

摘要： A composite resonance circuit is provided of which the resonance frequency range can be set with greater degrees of freedom with the peak frequency of the resonance characteristic curve of a resonance unit having good linearity and the resonance sharpness Q-factor being kept within a desired range. In the composite resonance circuit according to the present invention, first and second relay circuits are respectively connected between the resonance unit and first and second phase shift circuits that shift an input frequency signal by different phases. Hence, the resonance frequency range can be set by setting the gains and impedances of the first and second relay circuits according to its use, without changing resonance elements or the like of the resonance unit.

摘要： A composite resonance circuit is provided of which the resonance frequency is variable over a wide frequency range without changing the circuit constant of a non-resonant element having no resonance frequency. The composite resonance circuit comprises an input terminal; a resonance unit having first and second ports and quasi-resonating in response to AC signals respectively supplied to these ports; and phase shift circuits that perform different phase shifts on an AC signal supplied to the input terminal and supply first and second shifted signals subjected to the phase shift respectively to the first and second ports. The resonance unit is an impedance circuit that has at least four input terminals forming the first and second ports and that generates a quasi-resonant peak current under non-zero reactance in response to the first and second shifted signals coming in via the first and second ports. The quasi-resonant peak current is variable according to the frequency and phase shift quantities of the AC signals. Namely, the resonance frequency can be made to be variable.
