The technology has grown at an ultra-fast pace along with the world. Small devices with less power and high efficiency are in demand. As the circuit size gets smaller, the power requirement increases due to a greater number of transistors. A pre-scaler is a circuit which reduces the high frequency signal to a low frequency signal by integer division. A new approach to low power pre-scaler is proposed in this paper, which is an add-on to the conventional pre-scaler circuit. A true single-phase clock (TSPC) circuit reduces the skew problems in the clock and is used to realize latches and flip-flops. The objective of low power is fulfilled by incorporating the Adaptive Voltage Level Source (AVLS) to TSPC based circuit. The proposed AVLS-TSPC based pre-scaler was analyzed for a frequency of 10 MHz with a supply voltage of 1.8 V for both divide by 2 and 3 modes. The proposed pre-scaler consumes considerably lesser power when compared to that of the existing pre-scaler circuit. The circuits are implemented in 180 nm CMOS technology using Cadence Virtuoso and simulated using Cadence Spectre.
