OA is an operational amplifier, for example, NE5534, and are the BAV99 type diodes,  V.  mH,  nF,  kΩ,  Ω,  Ω,  Ω (),  Ω (external resistor 220 Ω in series with the coil ohmic resistance 55 Ω), = (24 + i) kΩ, , and  V. (b) The first-order RC chain. Note the negative resistor “,” used to compensate the positive buffer resistor of the network (see Figure 1). The value of the capacitor is specified in the caption to Figure 7.
