Abstract
The circuit preserves the available properties of LC ladder filter that are insensitive to component value drifts. Since all OTAs and capacitors are grounded, the circuit is insensitive to the disintegrated capacitor too. OTAs in the circuit possess identical transconductor values. The problem of large capacitor integration is also resolved by using OTA transformer
