Analysis of low voltage bulk-driven self-biased high swing cascode current mirror
A novel low voltage self-biased high swing cascode current mirror (SHCCM) employing bulk-driven NMOS transistors is proposed in this paper. The comparison with the conventional circuit reveals that the proposed bulk-driven circuit operates at lower voltages and provides enhanced bandwidth with improved output resistance. The proposed circuit is further modified by replacing the passive resistan...
متن کاملLow Voltage High Performance High Swing Cascode Current Mirror
A new very high performance low voltage cascode current mirror (CM) circuit is proposed in this work. The CM utilizes the low supply voltage and low input resistance characteristics of a cascode CM. In this CM, cascode configuration is used to obtain a wide operating current range and resistance compensation technique is incorporated to increase the operating bandwidth. The peaking in frequency...
متن کاملSelf Cascode Current Mirrors For Low Voltage Analog Circuits
A current mirror (CM) based on self cascode arrangement, useful for low voltage analog and mixed mode circuit is proposed. The CM uses 4 MOSFETs, has high input and output swing, operating at ± 0.5 V supply. Pspice simulations confirm the high performance of this CM having a bandwidth of 2.1 GHz. Resistive and capacitive compensations result in about threefold bandwidth increase to 6.1 GHz.
متن کاملDynamic Range of Low-Voltage Cascode Current Mirrors
Low-voltage cascode current mirrors are reviewed with respect to the design limitations imposed if all transistors in the mirror are required to operate in the saturation region. It is found that both a lower limit and an upper limit exist for the cascode transistor bias voltage. Further, the use of a signal dependent cascode bias voltage is discussed and a selfbiased cascode configuration is p...
متن کاملCascode Circuits for Low-voltage and Low-current Applications
Different cascode circuits are investigated with regard to their suitability for low-voltage and low-current circuits. A generalized circuit representation is introduced and different cascode circuits are discussed with respect to their small-signal parameters as well as their associated dynamic output ranges. The output voltage ranges for saturation operation of the different cascode circuits ...
