Title: Signal generator
Inventor: IIRU SHII HAAREIKUSON
IPC: H03C3/09
Filed: 1989-10-26
Abstract: PURPOSE: To minimize the phase noise by including a frequency locked loop FLL consisting of a delay line discriminator to measure the FM noise of the output signal of a VCO, and to feedback a frequency control signal to a line. CONSTITUTION: A PLL and the FLL are combined by coupling the output of a PLL gain amplifier 19 of a line 18 to a frequency discriminator variable phase shift network 25, and a PLL tuning voltage derived from an error signal by a PLL phase detector adjusts the phase shift of the variable phase shift network 25 to compensate the change of the output frequency of a VCO 11. Since the variation in frequency of the output signal of the VCO 11 is corrected, a profit of a high loop gain of the FLL is obtained. Thus, precise phase coherency is presented to a reference frequency, and an FLL having a narrow band width can be used because the phase noise in a small frequency offset from a carrier frequency is reduced.

Filed: 1984-12-27
Abstract: PURPOSE:To decrease current errors with simple constitution by making an emitter-collector voltage of the 1st and 3rd transistors (TRs) equal to make the early effect equal. CONSTITUTION:A returned current IC3 is expressed in an equation 1 when no early effect is taken into account. The emitter-collector voltage VCE2 of a TR3 is expressed as (VCC-VO), where VO is a voltage of a voltage source 5 and VCC is a power supply voltage 6, and in setting a shift voltage VS of a level shift circuit as VS=VO-(VBE2+VBE3), the collector-emitter voltage VCE1 of a TR1 is expressed in an equation 2, the emitter-collector voltage of the TRs 1, 3 is coincident, the result of K=1 is obtained and the error due to the early effect does not occur at all. Thus, as the theoretical error, the error in the equation 1 is a topic, and when hfe is 100, the error by the equation 1 is 0.02%, which is a very small error. Thus, a returned current with high accuracy is obtained regardless of simple and inexpensive constitution.
