Keywords: Low-voltage low-power rectifier Winner-take-all circuit Bulk-driven MOS transistor a b s t r a c t This paper introduces the novel design of a low-voltage low-power voltage rectifier based on bulk-driven (BD) winner-take-all (WTA) circuit. The proposed circuit is able to work as a half-or full-wave rectifier and it is specifically designed for(More)
A low-voltage variable gain amplifier based on PMOS bulk-driven input stage is presented in this paper. The gain of the proposed amplifier has a linear in-dB gain dependency since it utilizes the conventional pseudo exponential approximation function (l+x)/(l-x). The master-slave technique is used in order to control the voltage gain. The amplifier is(More)
Designing integrated circuits able to work under low-voltage (LV) low-power (LP) condition is currently undergoing a very considerable boom. Reducing voltage supply and power consumption of integrated circuits is crucial factor since in general it ensures the device reliability , prevents overheating of the circuits and in particular prolongs the operation(More)
