This paper presents frequency agile filter based on current difference transconductance amplifier (CDTA). The agile filters used in this work provide high agilty, tunability and quality factor while they are fully integrated configurations and not discrete systems. The use of grounded capacitors and resistor makes these structures suitable for integration.(More)
In this paper, a versatile modulator circuit that can be used for amplitude modulation, frequency modulation, delta modulation and sigma delta modulation has been proposed. The circuit has been implemented with the help of CDTA blocks, grounded capacitor and resistors. The circuit basically consists of an integrator, a Schmitt trigger and an inherent clock(More)
