Abstract
A system for use within an integrated circuit (IC) can include an input differential pair including a positive input node and a negative input node, a current source coupled to the input differential pair, and a current mirror. The current mirror can include at least a first active device and a second active device. The system can include a biasing transistor device having a source terminal coupled to a gate terminal of each of the first and second active devices, a gate terminal coupled to a drain terminal of the second active device, and a drain terminal coupled to a voltage source. The biasing transistor device is complementary to the current mirror.
