Title: Oscillation circuit
Inventor: KAGOHARA AKIO
IPC: H03B5/00
Filed: 1985-12-04
Abstract: PURPOSE:To obtain a desired oscillation frequency by using a split type delay element having a frequency split characteristic whose delay time is changed linearly with respect to frequency for the delay element. CONSTITUTION:The split type delay element 7 whose delay time is changed linearly with respect to frequency is used as a delay element in a delay feedback loop. The circuit is started at a frequency closest the center frequency of a band-pass filter 3 in the delay feedback loop among oscillation possible frequencies existing at an interval of 1/T, where T is a closed loop delay time the moment the delay feedback loop is closed and phi is the closed loop phase shift. In the oscillated frequency spectrum, the component at the center frequency of the band-pass filter 3 is grown, resulting that the delay time T of the loop is changed, the oscillated frequency is moved toward the center frequency of the band-pass filter 3, the two processes are generated continuously and the oscillated frequency spectrum is moved toward the center frequency of the band-pass filter 3 rapidly. Thus, the stable oscillation state is attained.

Title: Phase locked loop circuit
Inventor: SHIMURA KENJI
IPC: H03L7/093
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To improve the precision of an oscillation frequency from a phase locked loop(PLL) circuit. SOLUTION: The phase of a feedback signal (comparison signal) from a frequency divider 5 is compared with the phase of a reference signal Vi at a phase comparator section 1. A low-pass filter(LPF) 2 extracts a DC voltage from the phase comparison output. A DC voltage is given to a noninverting input (+) terminal of an operational amplifier 3 as a noninverting amplifier. On the other hand, a required negative voltage Bb (e.g. -1V) is applied to an inverting input (-) terminal of the operational amplifier 3 via a resistor R3. Thus, the operational amplifier provides an output of a voltage, including the negative voltage and a higher voltage is obtained from a conventional amplifier with the same amplification factor.  The amplified voltage is used for the control voltage of a voltage controlled oscillator(VCO) 4, resulting in that detects such as an insufficient control voltage is eliminated different from the conventional method of controlling directly the VCO with an output of an LPF. Thus, the precision of the oscillation frequency is improved, and the convergence to a required frequency is quickened.
