A novel non-overlapping signal generator intended for power-converters operation is presented. This switched capacitor circuit architecture-based sensor and actuator interface is implemented in AMS-H35B4D3 technology and consumes a power of 51.8 mW from a 3.3V-supply at 1 Mbps. Two-sided wide swing current source, two capacitors, Schmitt triggers and three transmission gates are employed on each side of the current source for implementing this versatile building block. The circuit provides needed dead-time to the power amplifier for high and low voltage applications. The time period of the master CLK is 1μs. The proposed circuit successfully generates two outputs with 0.4813 μs (∼half of period) non-overlapping delay between the phases. It occupies an area of 70 μm×180 μm from the total half bridge area of 800 μm×1370 μm.
