Low Voltage High Output Impedance Bulk-Driven Quasi-Floating Gate Self-Biased High-Swing Cascode Current Mirror

High-performance flipped voltage follower based low input resistance current mirror with wide current mirroring range and high output resistance

“…In the literature, various methods have been proposed to enable low voltage operation of current mirrors [16]. The various current mirrors based on these techniques that have been reported in literature are current mirrors based on floating-gate technique [17][18], current mirrors using bulk-driven technique [19][20], quasi-floating gate based current mirrors [21][22], current mirror based on both floating-gate and quasi floatinggate technique [23] and current mirrors using both bulk-driven and quasi-floating gate technique [24][25]. But these techniques suffer from the limitation of special fabrication steps.…”

A high output resistance, wide bandwidth, and low input resistance current mirror using flipped voltage follower cell

“…To meet today's industry demands, various current mirror structures using different techniques have been reported in the literature. [19][20][21][22][23][24][25][26][27][28][29][30] Madhushankara and Shetty 19 and Mishra et al 20 reported the Wilson current mirror and double cascode current mirror, respectively, using the floating gate technique. The floating gate technique lowers the requirement of supply voltage and hence reduces the power dissipation.…”

“…31 The bulk-driven self-biased cascode mirror (BDSBCM) has been reported by Aggarwal et al, 21 and the improved version of BDSBCM using a quasi-floating gate technique has been presented by Raj et al 22 However, both the mirrors 21,22 suffer from the limitations of high input resistance and low output resistance. Raj et al 23 overcome the limitation of the current mirror reported 22 by using a regulated cascode stage followed by a super cascode structure at the output of the mirror. The reported circuit offers high output resistance while consuming large power.…”
