The MPIV – Modular Pulsed IV is used for High Power current & voltage characterization of semiconductor devices. It is also well suited for applications requiring precise high current and voltage pulses. The Drain Pulse Module (DPM) uses an external high-current supply while the Gate Pulse Module (GPM) has an internal high-precision voltage supply. Additionally, the MPIV can be synchronized with an external or internal trigger.
The DPM is the core of the system. Its internal microcontroller uses precision Pulse Width Modulation (PWM) modules with complementary outputs and programmable dead-time in order to generate and synchronize the pulses for both drain and gate bias. The pulse width is adjustable from 200ns to 2ms; pulse repetition rate from 500Hz to 1MHz, with a maximum duty cycle of 50%. Two internal N-channel MOSFETs within the drain module support voltages up to 200V and currents up to 17A. Both the pulse and
quiescent bias voltages are delivered via external DC power supplies thereby making the Modular Pulsed IV a customizable solution.

Setup
The GPM operates as a slave module controlled by the DPM. Internal precision Digital Analog Converters (DAC) are used to adjust the gate voltage in the range of ±10V, with a 5mV resolution. The output buffer amplifier delivers up to 100mA.
Voltage and current measurements are performed using a high speed 4-channel digital oscilloscope. Voltages are sampled directly on the gate and drain bias-tee sense terminals; the drain current is measured using a high speed high sensitivity current probe.

The Focus Compact Model (FCM) utility is a streamlined software package designed to be used with Focus’ AURIGA high-end Pulsed-IV system, that is used to generate Compact Models for transistors from their Pulsed-IV and wideband pulsed s-parameter data.
This is achieved by generating a network of lumped circuit elements that represent accurately the fundamental linear & non-linear behavior of the device over a broad range of bias and power range.
The result of the modeling is a netlist and compatible with- the most common CAD tools used in RF Design; such as AWR Microwave office (MWO) and Keysight PathWave Advanced Design System (ADS).
Noise measurements allow the determination of the four Noise Parameters of a device (transistor). Focus’ Noise Modules integrate well with various third party noise receivers.
Noise Parameters: These are four numbers that fully describe the noise behaviour of an active or passive device (twoport) at a given frequency. For practical reasons we use the following quantities as Noise Parameters:
Focus’ noise parameter extraction routines leverage the PNA-X’s unique implementation
of the cold-source noise figure measurement technique. This specific technique requires a noise source to determine the kBG (gain-bandwidth constant) of the system and a passive mechanical tuner is used to characterize the noise receiver across both the impedance and frequency space. This step is imperative to obtain fully vector-source-corrected measurements.

A RF down conversion stage might be required if the frequency of noise measured exceeds the receiver’s bandwidth. Focus offers noise modules which support down conversion for optimal speed and performance.
