IHP 130nm Tech Narrowband 160 GHz LNA Factory¶
This notebook contains the parametrized cell-like factories for the generation of a 4-stage 160GHz narrowband (27 GHz) RF LNA.
The PCell is generated for a single stage, including parametric decoupling and matching RF MIM capacitors, parametric inductance stubs controlled through their length for biasing the decoupled nodes, parametric NPN BJT transistors and biasing resistors. For multiple stage approach, it is required to generate each stage and cascade them.

"""
Generates the layout for a single stage of a 160 GHz Low Noise Amplifier (LNA).
The stage includes input/output matching capacitors (RF MIM), a Bi-Polar
Junction Transistor (BJT) amplifier (NPN), biasing resistors (Rhigh/Rsil),
and associated passive routing structures (stubs, tapers, vias).
The layout is constructed by placing, rotating, and aligning component references,
followed by adding detailed routing, tapers, pins, and ports.
Args:
npn_emitter_width: Width of the NPN emitter finger (microns).
npn_emitter_length: Length of the NPN emitter finger (microns).
m: Multiplier for the NPN transistor (number of fingers/devices).
rows: Number of rows used for the via stacks connecting to the active device.
rfcmim_width: Width of the input MIM capacitor.
rfcmim_length: Length of the input MIM capacitor.
rfcmim_width2: Width of the output MIM capacitor.
rfcmim_length2: Length of the output MIM capacitor.
ymax_ref: Optional vertical reference coordinate (ymax) for the Rhigh resistor.
If None, defaults to the ymax of the input RF MIM.
emitter_stub_length: Length of the grounded emitter matching stub.
output_stub_length: Length of the grounded output matching stub.
bias_con_length: Length offset for the VBB bias connection rectangle.
# --- Layer Arguments ---
