DIFF Subgroup
H03B 7/06 active element being semiconductor device
Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Generation of oscillations using active element having a negative resistance between two of its electrodes > with frequency-determining element comprising lumped inductance and capacitance > active element being semiconductor device
CPC:
Generation of oscillations using active element having a negative resistance between two of its electrodes (H03B9/00 takes precedence) > with frequency-determining element comprising lumped inductance and capacitance > active element being semiconductor device
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
