Abstract: | In this paper a tunable waveform generator (WFG) architecture is presented. This architecture provides wide frequency tuning range and consumes less power, which makes it useful for low frequency instrumentation applications. The proposed WFG is designed in UMC 180-nm CMOS process technology with a single supply voltage of 1.8 V. Though the architecture utilizes conventional OTA based Schmitt trigger and gm-C integrator, it provides independent control over amplitude and frequency tuning. The amplitude tuning is also symmetric around the mid-rail voltage. The proposed scheme achieves peak to peak amplitude tuning of 0.35 V to 1.17 V and frequency tuning from 6.3 kHz to 2.7 MHz. |
