INTEGRATED NMOS-CIRCUIT ARRANGEMENTS:, ABSTRACT: The integrated NMOS-circuit arrangement is suitable for the connection of an external capacitor (C) in a voltage-controlled oscillator (VCO), whose frequency in the modulation range is linearly-dependent upon the control voltage (Ust) and whose sensitivity in the modulation range is independent of the control voltage (Ust). A switchable charging current source (11; M9) charges the capacitor (C) in a constant period of time at all working frequencies and a, switchable discharge current source (12; M4 to M8 M10, M11, R1), discharges the capacitor (C) in a time which is dependent upon the control voltage (Ust). The switch-over point is …
