A novel SC delay circuit is presented that is insensitive to the DC offset
and finite gain errors of operational amplifiers (OAs) as well as the capac
itance ratio mismatch. The effectiveness is illustrated and consolidated by
computer simulations. A comparison with typical compensated and uncompensa
ted circuits in terms of magnitude, phase and offset errors is also present
ed. The circuit is also further extended to realise a wideband and very acc
urate successive-anticipatory gain compensation scheme and to flexibly impl
ement arbitrary delay with only one OA.
