Abstract

Typical and proposed recycling folded cascade (RFC) amplifier have been designed in TSMC 0.18μm. Simulated and measured results are compared. Proposed RFC demonstrate an enhancement on DC gain by 5dB almost for the same power consumption and bandwidth. Moreover, it realized less input referred noise than typical. Split-length devices (SLD) method is applied on proposed (RFC) to create a low impedance node employed in indirect feedback compensation. Realization of two-stages recycling folded cascade amplifier using indirect feedback compensation method has been designed. The proposed two-stages amplifier delivers open loop gain 83dB enhanced by 20dB over typical one, gain bandwidth product is lS7MHz and slew rate is 74 V/μs which is required for reconfigurable multi-mode sigma-delta ADC to attain high SNR and SNDR.
