To produce copy of current flowing through active devices, from one end to other end of the circuit, current mirrors (CM) are used irrespective of loading effect. It’s indispensable part of an analog and mixed signal system including wide range of applications. In this paper various cascode current mirror circuits such as, an ultra-high compliance current mirror with low power consumption, a CM with extensive swing, a self-biased CM, and quasi-floating CM circuits are analyzed which includes: speed, power, input and output resistance, bandwidth etc. The comparison shows that ultra-high compliance cascode current mirror utilizes low voltage with relatively high frequency response and consumes less power while super cascode configuration is a good choice to obtain high output impedance for better performance, whereas quasi-floating gate MOS current mirror with resistive compensation can be used to enhance the circuit bandwidth. The various circuits are designed at 250 nm, 180 nm, and 130 nm CMOS technologies for justification of performance.

“…The purpose of current mirrors is to perform current amplification, active loading, signal level shifting and biasing (Azhari, Hassan, & Khalil, 2011). An ideal current mirror can be defined as an amplifier which ideally inverts the current or control it as a current-controlled current source (CCCS) (Hitesh & Goel, 2012).…”

We present a low power amplifier integrated with a wide swing cascode current mirror (WSCCM) based on PMOS transistors. To derive the low power amplifier a current of 120 uA is required, which is achieved by varying the widths of the transistors. The best result is achieved by varying the widths up to 6um with an output saturated current response of 120.04 uA. SECTPRE of CADENCE design tool is used as the design software to carry out the simulations. The proposed circuits are designed and verified in MIMOS 0.35 um CMOS and BSIM3 transistor model technology. The low power amplifier achieves an output response of 44.71 mV with a minimum power consumption of 0.485 mW.

SUMMARY This paper reports a novel high‐compliance, very accurate and ultra‐high output resistance current mirror. These features are achieved by employing a combination of negative and positive feedbacks in the proposed circuit. This makes the proposed current mirror unique in gathering ultra‐high output resistance, high compliance, and high accuracy ever demanded merits. The principle of operation of this structure is discussed, its main formulas are derived and its outstanding performance is verified by Cadence post‐layout simulations. Designed in the IBM 130‐nm standard CMOS process, the circuit consumes 230 × 110 µm2 of silicon area. Post‐layout simulation results indicate that with a 3.3‐V power supply, output voltage compliance of 0.93VSupply is achieved at a maximum output current of 96 μA. Moreover, an extremely ultra‐high output resistance of 320 GΩ is achieved, which is one of the highest reported values of output resistance for current mirrors implemented using regular CMOS technology. The −3 dB upper cut‐off frequency of the proposed circuit is 100 MHz and the output/input current transfer error is 0.1%. The whole circuit, including bias circuitry, consumes 0.57 mW when delivering 96 μA to the load. Copyright © 2014 John Wiley & Sons, Ltd.
