Abstract The development of high-efficiency capacitance multipliers and precision rectifiers for VLSI (Very Large-Scale Integration) systems is examined in this work, with a focus on low voltage operation. The major goal is to reduce supply voltage in order to consume energy as little as possible. It has been successfully created for the capacitance multiplier to work properly even with extremely low voltage supply, as low as 0.25 V. Class-AB current mirrors, which are renowned for their outstanding current efficiency, are used in the design. Experimental measurements were made on a 180-nm CMOS-based capacitance multiplier that obtained a multiplication factor of 11 in order to assess performance. The same class-AB current mirrors were also used in the same CMOS technology to construct low-voltage precision rectifiers. Over a hundred times more output current than quiescent current is produced by these rectifiers. Notably, both circuits function with 0.25 V supply and dissipate static power at a rate of only 100 nW. The work shows that low-voltage designs and class-AB current mirrors can be used to produce great performance and efficient power usage in VLSI systems.
