Abstract This paper presents a new class AB programmable square-root domain (SRD) filter.
The main advantages of the proposed circuits are low power consumption, wide input
dynamic range with small standby current and potential for low-voltage operation.
Simulation results confirm the validity of the proposed design technique and the high
performance of the proposed circuits.
Key-Words: Square-root domain, SRD filter, commanding filter, Log Domain filter
One of the figures of merit of a filter is the
dynamic range; this is the ratio of the
largest to the smallest signal that can be
applied at the input of the filter while
maintaining certain specified performance.
The dynamic range required in the filter
