This fully-uncoupled oscillator (i.e., having both CO and FO fully-uncoupled) uses
three ICCIIs and six grounded passive elements and is shown in Fig. 13.3 .
Assuming ideal ICCIIs, the proposed oscillator circuit in Fig. 13.3 has the
following CE:

y 1 y 4 þ y 2 y 5 y 3 y 5 ¼ 0 ð 13 : 5 Þ

From the above CE, two different versions of SRCO can be obtained by appropriate
choice(s) of elements:
