Abstract: PURPOSE:To satisfy a temperature compensation condition for a wide power voltage range and to supply a constant output potential without temperature dependency by looping back the current of a constant current source in the current mirror circuit of a P channel MOS transistor, and generating a different constant current source. CONSTITUTION:Since the base of a fourth NPN transistor Q4 is connected to the collector of a third NPN transistor Q3, and a fourth resistance R4 is connected between the emitter and a first potential, the transistor Q4 is the constant current source generating the constant current, which is looped back in the current mirror circuits CM of P channel transistor P1 and P2, and which comes to a third constant current I3. Since the third constant current I3 is generated by using the current mirror circuits CM of the P channel transistors, it is not affected by the temperature characteristic of the MOS transistor at all, and power voltage dependency is considerably improved. The temperature compensation condition is satisfied for the wide power voltage range, and the constant output potential without temperature dependency can be supplied from one end part of a first resistance R1.

Title: Variable phase shifter
Inventor: KAMIYA NOBUYUKI
IPC: H03H11/20
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To miniaturize a circuit by switching a case when a whole circuit is viewed to be series inductance being a phase lag circuit against a pass signal and a case when it is viewed as a series capacitor being a phase lead circuit and changing a pass phase so as to constitute a phase shifter. SOLUTION: When the phase of a high frequency signal inputted to an input terminal 11 and outputted from an output terminal 12 is made to be a reference, the high frequency signal inputted from the input terminal 11 changes by the phase obtained by adding the phase change of the inductor 14 and the capacitor 16 by making it pass through the inductor 14 and the capacitor 16. The signal is outputted from the output terminal 12. Since the inclination of the phase change by the frequency of phase quantity is opposite in the inductor and the capacitor, they are compensated and inclination by the frequency is prevented from becoming large. Thus, the variable phase shifter operates as that which can change the pass phase in four ways by changing the states of first FET 13 and second FET 15.
