フローティング電流源のための方法及び装置
Document Type and Number:
Japanese Patent JP6436982
Kind Code:
B2
Abstract:
As taught herein, a floating current source outputs a load biasing current from a source terminal into an external load which may have a variable resistance, and sinks the load biasing current from the load into a sink terminal. Advantageously, the floating current source includes a single-transistor current sink having a bias control that sets the magnitude of the load biasing current desired, and further includes a single-transistor current source that self-biases from the float voltage developed on the external load to an operating point at which the single-transistor current source sources the desired magnitude of load biasing current. One or more AC shunts within the self-biasing network prevent any AC fluctuations present or impressed on the source terminal of the floating current source from changing the operating point of the single-transistor current source, thereby imparting a high effective impedance to the single-transistor current source.
