Understanding and Applying Current-Mode Control Theory
www.ti.comFigure 3. Peak current-mode sub-harmonic oscillation. For D<0.5, sub-harmonic oscillation is damped. For D>0.5, sub-harmonic oscillation builds with insufficient slope compensation. By adding a compensating ramp equal to the down-slope of the inductor current, any tendency toward sub-harmonic oscillation is damped within one switching cycle.

www.analog.comBASIC LINEAR DESIGN 2.2 One of the first totally monolithic implementations of these functions was the Precision Monolithics, Inc. BUF03 shown below in Figure 2.2 (see Reference 1). PMI is now a division of Analog Devices. This open-loop IC buffer achieved a bandwidth of about 50 MHz for a 2 V peak-to-peak signal.
