Abstract: A circuit and method for a saturation correction of a power amplifier (PA) is provided in order to maintain a desirable switching spectrum. The circuit includes a closed loop system that is responsive to a dynamic PA control signal known as VRAMP. The method samples a detector voltage that represents the output of the PA at the maximum voltage level of VRAMP. The sampled detector voltage is then reduced by a predetermined amount and applied as a fixed voltage PA control signal in the place of VRAMP. As a result, the closed loop system responds to the fixed voltage PA control signal to bring the PA out of saturation before VRAMP can begin a voltage decrease. Once the VRAMP voltage decreases, VRAMP is reapplied as a dynamic PA control signal in place of the fixed voltage control signal.

Abstract: Apparatus for feeding livestock comprises a pan accessible to the livestock for feeding therefrom, a container for holding a quantity of feed comprising dry powdered feed material and a mixing chamber. A dispensing mechanism dispenses measured increments of the feed to the mixing chamber and a control valve is coupled with a water supply line for dispensing measured increments of water to the mixing chamber. A mixer is selectively operable for mixing the water with the feed to produce a fluid feed mixture for delivery into the pan.
