- Bandgap Reference Layout for Mechanical Stress Voltage Shift Mitigation
Spatially separated BJT arrays in a bandgap reference cancel solder stress-induced voltage shifts without extra compensation circuitry.
- Dynamic Biasing in Stacked I/O Drivers for 3.3V Stress Protection
Dynamic gate biasing lets stacked 1.5V I/O transistors safely drive 3.3V signals without terminal overstress or reliability loss.
- Current Sensing Circuit With Off-State Voltage Matching
A switch equalizes sense and drive transistor voltages during off-states, preserving current ratio accuracy without a shunt resistor.
- Back-to-Back Power Switch Gate Control for Zero-Current Turn-On
An amplifier-generated gate offset enables zero-current turn-on in back-to-back power switches while stabilizing on-resistance across variations.
- Controller Protection Circuit for Defective Transistor Overvoltage Detection
Monitored feedback loops detect defective output transistors and clamp overvoltage or undervoltage before controller logic and loads are damaged.
- Power Switch Turn-Off Control with Bias-Triggered Gate Discharge
A bias-triggered discharge path reduces gate-to-output voltage during turn-off, helping prevent power switch damage and burnout.
- RF Voltage Generation Circuit for Low-Loss Transmission Path Control
Control-signal voltages are converted into regulated RF drive voltages to switch transmission paths with lower voltage loss.
- Signal Driver Fault Detection for Feedback Instability Control
Current-threshold monitoring detects stabilization faults and decouples feedback to keep a signal driver stable during oscillation risk.
- PMOS Headswitch Gate Biasing for Leakage Reduction
A voltage generator drives PMOS headswitches into super-cutoff to curb off-state leakage in power-gated domains and extend battery life.
- Bootstrapped Switch Circuit for Gate-Induced Drain Leakage Control
A protection circuit clamps drain voltages in bootstrapped switches to suppress GIDL, reducing leakage, ON resistance, and voltage droop.
- P-Channel MOSFET Driver Circuit Against Inductive False Switching
A P-channel MOSFET driver uses voltage dividers and sub-transistors to block inductive false switching and keep ON-OFF control stable.
- Power Switch Circuit with Default Gate Voltage for Fast Source Switchover
A held default gate voltage and staged charge pumping speed turn-on, keeping output voltage above safe levels during external power switchover.
- RF Front-End Switch Biasing for Leakage and Linearity Control
Negative rectifier biasing and closed-loop substrate control cut RF switch leakage and non-linear distortion in multi-band front ends.
- Current Detection Circuit With Mediated Leakage Isolation
A normally-off intermediary switch blocks leakage, while drain-voltage division stabilizes output current detection against on-resistance variation.
- OTA Pre-Driver Circuit for Precise MOSFET Gate Voltage Shaping
An OTA voltage-follower pre-driver continuously regulates MOSFET gate voltage to improve stability and transient response with capacitive loads.
