摘要： A circuit is provided having a differential difference amplifier (DDA) having first and second inputs to receive a desired body bias signal, and a third input to receive a supply voltage, the DDA configured to generate an intermediate output signal, the intermediate output signal coupled to an output buffer generating an output signal having a desired gain, the DDA having a fourth input, to cause the output signal to reference to variations in the supply voltage.

摘要： A cavitation enhanced atomizing process comprises forming a flowing solution of the liquid to be atomized and a lower boiling cavitating liquid. This flowing solution is then contacted with a pressure reducing means, at a temperature below the bubble point of the cavitating liquid in the solution, to produce cavitation bubbles. These bubbles comprise cavitation liquid vapor and the bubble nucleation produces a two-phase fluid of the bubbles and liquid solution. The two-phase fluid is passed downstream into and through an atomizing means, such as an orifice, and into a lower pressure atomizing zone, in which the bubbles vaporize to form a spray of liquid droplets. The nucleated bubbles also grow in size as the so-formed two-phase fluid passes downstream to and through the atomizing means.
