Latest Patents
One of Marshall's key patents is the "Voltage Controlled Integrated Circuit Astable Multivibrator." This invention discloses an integrated circuit voltage-controlled astable multivibrator that utilizes external fixed components, specifically resistor RT and capacitor CT. The multivibrator's center frequency is determined by the value of capacitor CT, the amplitude of a constant current Il used to charge and discharge capacitor CT, and a voltage VT. The timing period is proportional to VT/Il, where VT represents half the voltage swing across capacitor CT. To minimize undesired frequency variations, both current Il and voltage VT are generated in similar matched networks from the same voltage source, ensuring that they track each other effectively.
