Abstract
This paper proposes a low-voltage current-mode integrator for a continuous-time current-mode baseband channel selection filter. The low-voltage current-mode linear cascode integrator is introduced to offer advantages of high current gain and improved unity-gain frequency. The proposed current-mode integrator has fully differential input and output structure consisting of CMOS complementary circuit. Additional cascode transistors which are operated in linear region are inserted for bias to achieve the low-voltage feature. Frequency range is also controllable by selecting proper bias voltage. From simulation results, it can be noticed that the implemented integrator achieves design specification such as low-voltage operation, current gain, and unity gain frequency.
