摘要
The various embodiments utilize cascode circuits in dual-threshold-voltage (dual-VT), BiCMOS and DTMOS technologies. The circuit topologies include cascode-connected transistors in the output branch of a current mirror and as a cascode amplifier. Such configurations are capable of both high output impedance and high output swing. The cascode circuits of the various embodiments are operable without separate gate-bias voltages for the cascode-connected transistors. The current mirrors can be used in circuits requiring a regulated current or other current mirroring applications. The current mirrors can further be used as active loads, such as an active load for an amplifier.
