Abstract :
A 3rd-order fully-differential continuous time elliptic filter is presented which is composed of widely-linear input V-I converters with a minimum supply voltage of 1.5 V and 1% THD for rail-to- rail input swing. In a 1.2 μm n-well CMOS process, this filter can achieve 3dB frequency of 163 kHz with only 138 μW power dissipation at 1.5 V supply voltage. THD with 50 kHz 1Vpp fully-differential input signal is 1.8%
