This paper proposes a high data rate, low-power, low-voltage design of OTA-based M-ary ASK, FSK and QAM modulator and demodulator circuits. Conventional D/A converter of M-ary circuit has been replaced with the operational transconductance ampli ̄er-based n-bits to 2n level converter which operates with input frequencies up to 2.1GHz. OTA-based oscillator(More)
This paper demonstrates a design of 2 GHz integrator circuit using a feed forward-regulated cascode OTA. The design of integrator circuit using OP-AMP seldom works up to Mega-Hertz range. Operational Transconductance Amplifier, having an advantage of tuning the transconductance using external current source, finds huge amount of applications in the field of(More)
