摘要： A method and circuit for activating a liquid crystal matrix display panel in which during each selecting period, each liquid crystal cell pixel of the matrix, whether selected or unselected, receives either a primary selecting signal voltage or non-selecting signal voltage as well as an additional different secondary voltage to generate substantially homogeneous crosstalk noise over the entire display. The signal voltage applied to a pixel during a selecting period can vary between a primary selecting or non-selecting voltage applied for a first time interval followed by or preceded by a secondary voltage intermediate the selecting and non-selecting voltage applied for a second interval. Alternatively, the primary signal voltage applied to the pixel for a first time interval can be a selecting or non-selecting voltage and secondary voltage applied for a second time interval can be the other. In another embodiment of the invention, the relative duration of the primary and secondary voltages affects the darkness gradation of the display.

摘要： A variable capacitance circuit comprising a capacitor array, associated switching elements and transient impedance varying circuits. The capacitor array comprises a plurality of capacitor elements connected to a common node coupled to a crystal oscillator in a crystal oscillator portion and each capacitor element includes a connected switching element that controls activation of selected capacitor elements that are selectively placed in operation as load capacitance with the crystal oscillator to change and adjust its frequency. Further, circuits are provided in a temperature compensation portion to selectively control the activation of the switching elements based upon decoded compensating values provided in memory, such as based upon sensed oscillator temperature conditions. The transient impedance varying circuits comprise multi-level voltage generating circuits for changing the continuity impedance of activated switching elements, among switching elements being switched, to another impedance level or one of a plurality of additional impedance levels. As a result, an intermediate impedance value can be created between the ON and OFF states of the switching elements so that there is no rapid change in the total equivalent capacitance imposed by the capacitor array on the oscillator resulting in smooth capacitance switching which corresponds to smoother frequency adjustment of oscillator output.

摘要： An oscillator circuit wherein the impedance at the output terminal can be selectively decreased for a short period of time to thereby increase the closed loop gain is provided. The oscillator circuit includes a quartz crystal vibrator and a C-MOS inverter having a drain output terminal for producing a high frequency signal thereat, the gate output terminal being fed back through the quartz crystal vibrator to a gate input terminal to define a predetermined closed loop gain. The invention is particularly characterized by a control circuit external to the oscillator circuit that is adapted to produce a control signal for a predetermined period of time. A secondary inverter is provided and is adapted to be selectively coupled, in parallel, with the C-MOS inverter during the period of time that the control signal is applied thereto, to thereby reduce the impedance at the output terminal of the C-MOS inverter and increase the closed loop gain during the predetermined period of time that the control signal is applied thereto.
