Abstract
Abstract A pulse amplifier circuit comprises a pair of switching stages operatively connected between an input node and a signal node. Each switching stage is respectively actuated by signals derived from the leading and trailing edges of the input pulse, the signal node being charged between its two levels as a result of the alternate conduction of the switching stages. Neither switching stage is conductive in the period between the charging cycles of the signal node, the signal level at that node remaining substantially quiescent during that period.
