Abstract
A plurality of inverted transitor current mirror and pull down circuits are disclosed which are suitable for providing current mirroring and base pull down functions in a variety of integrated circuit applications. The use of the inverted transistor as a current mirror is also utilized in gaining and/or level shifting any differential or single-ended analog or digital signal. The use of a multiple emitter inverted transistor for providing multiple pull down reduces to a fraction the chip area otherwise required by the use of multiple transistors.
