Addition of D1 and R4 to astable MVBR connection of 741 or equivalent opamp results in two different charging rates for C1, depending on whether opamp is in positive or negative saturation. Positive and negative peaks of output pulse then have different widths.-R. Melen and H. Garland, Understanding IC Operational Amplifiers, Howard W. Sams, Indianapolis, IN, 2nd Ed., 1978, p 122-123.
