GaAs pHEMT bias and sequencing controller
Maturity plannedTargets III-V processDifficulty MediumPriority 1
Gate and drain bias generator with negative gate supply sequencing that protects depletion-mode pHEMT amplifiers at power-up.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| vg | inout | analog | 4 | |
| vd_en | out | parallel | 4 |
Standards
No external standard applies.
Notes
For Dyber, Inc. GaAs pHEMT front ends; CMOS or GaAs implementation.
