In this paper, we show the Field Programmable Charge Pump (FPCP) concept in which the FPGA concept is applied to Charge Pump DC-DC converters. With this scheme, a fully programmable circuit is obtained to implement any Charge Pump topology and voltage conversion ratio with the same circuit. According to presented simulation results, the FPCP has only a slight performance loss due to programmability...
The present article is related to the recently published paper given in Singh (Analog Integr Circuits Signal Process, 62, 327–332, 2010), which depicts the failure of Barkhausen criterion concerning the determination of condition of oscillation for startup of sinusoidal oscillation. In particular, the sinusoidal oscillator circuit considered in this article is one of the possible four alternatives...
