“…These baseband filters are sensitive to variation of design process and temperature. To overcome this problem, the current-mode design method has been discussed in various researches [6,7]. Because of a small internal voltage, the current-mode circuit requires low supply voltage and consumes low power.…”

Abstract:A low-voltage current-mode integrator is presented for a continuous-time baseband channel selection filter of wireless communication systems. Fully-balanced current-mirror structure with additional cascode transistors operated in linear region enables low-voltage and low-power dissipation properties as well as voltage-controllable cutoff frequencies over a broad frequency range. A channel selection filter using the proposed integrator for three different communication standards with direct conversion receiver is implemented for a design example. Experimental results show that the implemented channel selection filter achieves design specification and outperforms other conventional filters.

“…Linear transformation (LT) high-order active filters have the advantage that every section of the original LC ladder prototype can be realized by using active elements individually [19,20]. Also, voltage-mode high-order LT MOSFET-C filters using OTRAs are presented in [21].…”

SUMMARYIn this paper, third-order current-mode MOSFET-C filters that use operational transresistance amplifiers (OTRAs) with little parasitic capacitance effects are presented. On the basis of the proposed systematic method and design procedure, we can efficiently synthesize third-order active filters with OTRAs along with simplified MOSFET resistor circuits, and all virtually grounded capacitors. Third-order currentmode Chebychev low-pass and high-pass filters are realized to verify the validity of the theoretical analysis. Experimental results employing commercially available current feedback amplifiers are also given.
