Figure 10.3. This CMOS pulse generator (a) is not recommended because, with the values shown, it over-
drives the gate inputs excessivelyas the waveforms of (b) indicate.
T '::E ALL GATES ARE CMOS.
Figure 10.4. The addition of resistors to the circuit of Figure 10.3 (a) helps reduce overdrive, but the
addition of diode clamps in the shunt leg of the attenuators (b) is even more effective. If you
have two 2-input NAND gates available, the circuit of (c) is the best implementation.
