Abstract
A current source circuit includes an initial bias generator and a diode-connected first metal oxide semiconductor (MOS) transistor having a gate, a source, and a drain. The drain of the diode-connected MOS transistor is connected to the initial bias generator. The current source circuit also includes a second MOS transistor, a first resistor, and a current mirror. The second MOS transistor has a gate connected to the gate and drain of the diode-connected first MOS transistor. The first resistor is coupled between a source of the second MOS transistor and a ground node. The current mirror is coupled to a drain of the second MOS transistor and generates bias current for other components within the current source circuit.
