FIELD: radio engineering; high-quality delay lines, phase shifters, and delay equalizers. ^ SUBSTANCE: in order to enhance dynamic range and stability of third-order phase section in ARLC hardware base, capacitor C2 is connected in parallel with inductance element L1, both connected at one point to ground and at other one, through first capacitor C1 to non-inverting input of operational amplifier mu; the latter is connected through first resistor R1 to input of phase section and the latter is connected through second resistor R2 to inverting input of operational amplifier mu; this amplifier is connected through third resistor R3 to operational amplifier output that also functions as phase section output. ^ EFFECT: reduced active sensitivity value. ^ 1 cl, 5 dwg |
