Tangent corrected saw-tooth voltage generator - has output amplifier controlled by vertical frequency saw-tooth and parabolic voltage

摘要

The vertical frequency parabolic voltage and a first reference voltage are applied to the bases of two transistors and the first reference voltage is applied to the bases of another two transistors. The vertical frequency sawtooth voltage and a second reference voltage are applied to the base of a fifth transistor and the second reference voltage is applied to the base of a sixth transistor. The emitters of the first two transistors are connected through a resistor each to the collector of the fifth transistor, and the emitters of the other transistors pair are connected through a resistor each to the sixth transistor collector. The emitters of the fifth and sixth transistor are connected through a resistor each to the reference potential. The collectors of two transistors are connected to the output for the tangent corrected sawtooth voltage, and through a common resistor to a supply potential. The collectors of another transistor pair are connected through a common resistor to the supply potential.
