All Pass Filter using DTMOS Technique

In this paper, All Pass Filter is designed using the Dynamic Threshold MOS Transistor (DTMOS) technique. The proposed filter is operable at very low voltage and comprising many advantages over the existing all pass filters. In this work, two external elements are used: one resistor and one capacitor, the resistor can be used as active elements so that it can be implemented on a chip. For simulation purposes, PSPICE simulation using 0.18μm technology is deployed. The power supply used is ±0.2V. The proposed device dissipate lower power i.e. 0.53μW, and has high output impedance. Due to this, the device can be cascaded to design other applications such as oscillators.
