Typical circuits with OP AMP interfacial input and bipolar/VMOS current amplifier outputs are sketched. Attention is drawn to such circuit refinements as (i) augmenting differentiator for minimising sweep delay; (ii) linearizer to compensate for nonlinearity due to core saturation; and (iii) low noise, low drift and minimal voltage pushing options.
